Description

Field of the invention

[0001] The present invention relates generally to the field of recorders, and more particularly to a recorder having provisions for scale length compaction to provide a relatively long cavity in which a column of air can vibrate longitudinally to produce sound, while maintaining compact external dimensions of the recorder. State of the art

[0002] Recorders are long musical instruments relative to their bore diameter. The bore refers to an elongated hollow space within which a column of air vibrates longitudinally, generating sound. It is defined by a pressure-tight exterior, the geometry of which is determined by musical and technical requirements.

[0003] This diameter-to-length ratio makes low recorders, in particular, very long and difficult to grip due to the necessary wide fingerhole spacing. Such recorders are also heavy and must be assembled from several sections before playing. The tightness of the joints between the sections is extremely problematic. Leaks, e.g., due to changes in humidity, wood warping, etc., quickly reduce the instrument's response. Good response means that the note is easier to play, since not only a precisely defined blowing pressure is required, but a wider range of blowing pressure is sufficient.

[0004] In order to be able to play low recorders from an anthropometric perspective, in addition to keys, scale length compactions (often erroneously referred to as shortening) must be used. There are several different approaches to scale length compactions in the history of woodwind instruments, which are briefly outlined below. Bends and bends:

[0005] Kinks and bends are a common feature of scale length compaction. Parallel and / or counter-rotating drilling into a volume:

[0006] Bassoons, rankets, column flutes, and dulcian instruments feature parallel tubes drilled into a solid volume, connected at the ends by hollow chambers, typically allowing 180° turns. This allows for a compact bore length, but at the expense of the weight-to-volume ratio. Meanderings:

[0007] In the case of a Serpent, for example, the serpentine winding scale is realized by case halves carved out of solid wooden parts, whereby the compactness of the instrument results solely from the distribution of the length in space (meandering), but not from a multiple use of the scale's inner walls (i.e. from a front and back of the same scale's inner wall).

[0008] Or the bass clarinet by Nicola Papalini, circa 1815, where a narrow, serpentine bore, divided into two halves, compacts the instrument in a limited section. The shape of the bore cross-section is based on a rounded, drilled shape.

[0009] A special design is the Venova, introduced by Yamaha Corporation in 2017. It's not a recorder, but a type of saxophone, and is made of plastic. However, it also features a compacted scale design. Here, too, the scale, which has a rounded cross-section, is simply compressed into a serpentine shape.

[0010] Another current example of meandering compaction is the subbass recorder by Moeck Musikinstrumente + Verlag GmbH, model 5741 Subbass, which is manufactured using the multi-shell technique. In this case, only the upper part of the bore is compacted. Due to the mouthpiece, which is positioned strongly upwards in this design, the player is either unable to blow straight with their oral cavity or forced to place the instrument at an awkward angle, diagonally downwards, past their twisted upper body. Furthermore, the view, at least downwards, for notation purposes, is restricted by the bore section extending upwards beyond the mouthpiece. Kinks in rectangular scales made of sheet materials:

[0011] Organ building has always featured bores with a rectangular (usually square) cross-section, made from flat materials such as wooden boards, wood panels, or similar. Compact versions of this bore and construction have also been known in organ building for a very long time. There are also saxophones with a bent bore made from wood panels.

[0012] A special type of recorder of this design is the so-called Paetzold flute, originally developed by Joachim Paetzold and currently manufactured and further developed by Kunath Instrumentenbau. In this flute, which is primarily produced in the lower registers, the scale length in its original form is achieved by rectangularly joined plate materials. The well-known compaction technique of bending a rectangular scale length can also be found on this flute. There are also multiple-used inner walls. However, it is designed in such a way that either only the head of the flute or the foot of the flute is compacted (redirected), and the scale cross-section is always rectangular and, due to its design, can only be changed within limits. A defining feature of this flute design and, with regard to the key design, essential is that the scale area containing the finger holes is essentially straight in a single line.Compaction is not intended for this scale section. The Paetzold sub-double bass does have a scale section bordering more than one common partition, but only to a limited extent. All low instruments are designed in such a way that they must be played while standing or sitting on the floor, vertically or freely supported, in front of the player, or held at the side of the twisted body.

[0013] The flutes of this type produced using generative manufacturing essentially use the same geometric concept and therefore represent the same state of the art with regard to the compaction of the scale length.

[0014] Non-compacted low recorders cannot be played directly, but only with a blowpipe, which is disadvantageous. This prevents the desired shaping of the sound through the mouth cavity.

[0015] Traditional designs with compaction, for example, through parallel holes, are inefficient in terms of required installation space and material usage (weight). The space and dimensions of the instruments are large, and such instruments are comparatively heavy. Highly compact geometries cannot be realized through pure meandering.

[0016] The use of sheet materials (see Paetzold) inherently imposes very limited flexibility in the design of the scale. Thus, advantageous geometric changes, such as jumps, curves, and discontinuous cross-sectional changes, are difficult or even impossible to implement in a highly flexible scale.

[0017] The Fig. 4b and Fig. 5b show a conventional deep recorder 300, in the example a so-called great bass, with a headpiece 301 with a beak 303 for blowing the recorder 300, a relatively long main body 302 and an end piece with a sound hole 304. As in the Fig. 5b, pitch-setting sections 322a, 322b are provided in or on the main body 321. The pitch-setting section 322a has, according to the Fig. 5b has a first tone hole 323a or a plurality of tone holes 323a, respectively, wherein a key mechanism 325a is provided, which comprises a plurality of keys or pushers 324a, which, when actuated via the key mechanism 325a, act on a plurality of second tone holes (not shown). The second tone holes can be located further away from an ergonomic finger position, i.e., cannot be reached with the normally available finger spread. The first tone hole 323a can be covered without a key or pusher, i.e., by means of a finger.

[0018] In the manner of the first tone hole 323a, according to the Fig. 5b for the right hand, a further first tone hole 323b or a plurality of first tone holes 323b may be provided at a suitable position, with an associated pitch-setting section 322b, to which a key mechanism 325b may be associated, which may comprise a plurality of keys or pushers 324b, which, when actuated via the key mechanism 325b, can act on a plurality of second tone holes (not shown).

[0019] Despite long key levers, even semi-compacted, low recorders usually have hand positions where, especially for the low hand, an unnatural and tiring bending of the wrist (radial adduction, i.e. bending towards the thumb) is necessary for the intended use of the instrument, as indicated by the reference number 310 in the Fig. 5b indicated.

[0020] Another disadvantage is that low flutes are usually placed statically either in front of the player on the floor and the player, standing or sitting, has to literally adjust to the instrument, or the instrument cannot be held straight in front of the body, but only to the side of the slightly twisted upper body.

[0021] In addition to the increasing sealing problems described above with the increase in the number of instrument parts, the large number of parts also has a negative impact on handling, as comparatively large cases are required, which are difficult to transport.

[0022] On stage or in an orchestra, long, assembled instruments must be positioned either upright or lying down. Standing upright poses a particular risk of elongated instruments falling over, while lying down poses a particular risk of tripping over them. Summary of the invention

[0023] The object of the present invention is to provide a recorder that at least partially remedies the aforementioned problems and disadvantages. In particular, a recorder for low notes with improved ergonomic handling is to be provided.

[0024] The object is achieved by a recorder having the features of claim 1 and 9, respectively. Further advantageous embodiments are the subject of the dependent claims.

[0025] According to a first aspect, the present invention provides a recorder, in particular a recorder with a sounding length of at least 870 mm, comprising a headpiece with a blowing edge for generating a vibrating air column and a main body having a bore in which the air column vibrates to generate sound, and at least one pitch-setting section for determining the frequency of the vibrating air column, wherein at least one section with a non-rectilinear bore guide is provided in the main body. According to the invention, the overall height of the recorder, namely the distance between the wind channel entrance and the underside of the instrument, is less than 800 mm. A recorder according to the present invention is thus particularly suitable for playing while seated and is characterized by a very compact design.In particular, highly compact designs can be realized that can be played directly (without a blowing tube), held vertically in front of the body without upper body torsion, played while sitting and also placed on the lap.

[0026] The invention thus achieves this objective by compacting the instrument along its entire length by utilizing multiple walls, minus the necessary bore length for the mouth-hand distance. This bore compaction can occur in several horizontally and / or vertically meandering directions, but can also be achieved by placing bore sections side by side (making the instrument wider) or one behind the other (making the instrument deeper). The bore cross-section can be freely adapted to requirements over the entire bore length.

[0027] This allows for the ergonomic arrangement of pitch-control sections for easy playing and handling. These pitch-control sections are particularly long enough to allow for single-handed operation with appropriate positions of the left and right hands relative to each other. To achieve the required pitches, several tone holes can be controlled by keys or pushers and a key mechanism, allowing them to be covered or opened.

[0028] According to a further embodiment, the main body has at least one bore wall, the two sides of which, namely the front and rear, define the oscillating air column. This can be achieved by means of meandering wall sections, but also by means of reversal areas for the oscillating air column.

[0029] According to a further embodiment, the pitch-determining section has a first tone hole and / or a plurality of keys or pushers which, when actuated via a key mechanism, act on a plurality of second tone holes, wherein the second tone holes are located further away from an ergonomic finger position, in particular at distances which no longer allow easy playing with the fingers of one hand, or in which at least one section with a non-rectilinear scale guide is provided.

[0030] According to a further embodiment, the section of the headpiece with a straight scale guide has a total length of 200 mm to 400 mm. The headpiece is designed without a bend for optimal sound production, thus preferably being straight.

[0031] According to a further embodiment, the cross-sectional shape of the scale varies over the entire scale length, with the specific cross-sectional shape being tailored to the desired conditions for tone production. Thus, according to the invention, the cross-sectional shape of the scale can be freely adapted to the structural and playing requirements in terms of position and space. In particular, it is possible to realize very narrow or wide, flat, round or rounded, continuous or discontinuous, or otherwise deviating from the drilled shape.

[0032] According to a further embodiment, the area where a player's hand grips the instrument is provided with ergonomically advantageous flattened portions, in particular with wide, flat scale sections. This enables particularly ergonomically advantageous playing.

[0033] According to a further embodiment, the recorder has only a single joint for assembling the instrument, in particular a detachable cork connection between the head joint and the main body.

[0034] According to a further aspect of the present invention, a recorder, in particular a recorder with a sounding length of at least 870 mm, is provided with a headpiece having a blowing edge for generating a vibrating air column and a main body having a bore in which the air column vibrates to generate sound. According to the invention, at least two bore sections are formed on the main body, each defining a change in the direction of the bore, wherein at least one bore section defining such a change in the direction of the bore has a bore wall whose front and back sides delimit the vibrating air column.

[0035] By using multiple walls in this way, i.e., sharing the front and back of a partition, the scale can be compacted, resulting in a significant reduction in the overall length of the instrument. In particular, minus the scale length required for the mouth-hand distance, the instrument can be compacted along its entire length. This scale compaction can occur in several horizontally and / or vertically meandering directions, but can also be achieved by placing scale sections side by side (making the instrument wider) or one behind the other (making the instrument deeper). The shape of the scale cross-section can be freely adapted to requirements over the entire scale length. Figure overview

[0038] According to the Fig. 1, the recorder 30, in particular designed as a recorder with a sounding length of at least 870 mm, has a head joint 20 and a main body 7 (cf. Fig. 4a), of which one housing half 21a is shown in full and another housing half 21b is shown only partially, wherein the main body 7 in the illustrated embodiment is box-shaped or cuboid-shaped. In this example, the main body 7 is formed by two cuboid-shaped housing halves 21a, 21b (cf. Fig. 6), each of which may have a flat upper surface facing the outside of the housing and which are connected to one another, for example by means of gluing, adhesive bonding, or sealed screwing. The bore 1 may expediently be formed exclusively in one of the two housing halves 21a, 21b, but may also be formed in both housing halves 21a, 21b with any desired division of the respective portions. For this purpose, a channel is formed in the respective housing half, which channel extends continuously from the connecting area between the head piece 20 and the main body 7 to an exhaust opening provided on the main body 7, the so-called sound hole (cf. Fig. 7a, reference numeral 21c).

[0039] As will be apparent to the person skilled in the art, the top or back of the respective housing half can also be non-planar, for example in a direction perpendicular to the direction shown in the Fig. 6 shown top or back side may be provided with a projection which may, for example, be convex or concave.

[0040] The headpiece 20, which is connected to the main body 7 at the upper end, forms a wind channel to which an air stream is fed, which impinges on a cutting edge (blowing edge), which is essential for the sound production of the recorder. The headpiece 20 is linear, in particular without kinks. The headpiece 20 and the main body 7 are connected to each other via a joint, in particular a detachable cork joint. Further joints are expediently not provided in a recorder according to the present invention.

[0041] Formed in the lower housing half 21a is a bore 1 in which the air column vibrates to generate sound. In the direction of travel of the vibrating air column formed therein, this is delimited by multi-purpose walls 2a-2g, as described in more detail below. More specifically, in the direction of travel of the vibrating air column, the front and rear sides of partition walls 2a-2g delimit the vibrating air column, whereas in the direction perpendicular thereto, the bore 1 is delimited by a front and rear side of the respective housing half 21a, 21b of the main body 7.

[0042] The Fig. 2 shows an example of the scale 1 of the embodiment according to the Fig. 1. This has widenings and narrowings depending on acoustic or ergonomic requirements, as explained in more detail below, and can also include horizontally meandering scale sections and / or vertically meandering scale sections. Furthermore, rounded or curved shapes can be provided in the area of ​​a change in the direction of scale 1, in the example according to the Fig. 2 in the lower reversal area.

[0043] According to the invention, the bore 1 can be compacted by multiple use of the walls 2a-2g, thus significantly reducing the overall length of the main body 7. This can be done in one or more horizontally meandering bore areas as well as in one or more vertically meandering bore areas. These bore areas can be arranged next to one another, which widens the main body 7 of the instrument, but can also be arranged one behind the other when viewed in a given direction, which makes the main body 7 of the instrument deeper. The cross-sectional shape of the bore 4 can be freely adapted to requirements over the entire bore length, as explained in more detail below and exemplified in the Fig. 3 indicated by the different sized cross sections 4a-4c.

[0044] How to Fig. 1 and Fig. As can be readily seen from Figure 2, the bore 1 is formed entirely from several sections 100a-100n, in each of which the direction of the air column oscillating therein is changed by the interaction either between a partition wall and an opposite side wall section of at least one housing half 21a, 21b or between two opposing partition walls, or the bore guide does not run in a straight line. In the illustrated embodiment, this change in direction is essentially 90 degrees in some sections, but the present invention is not intended to be limited to this.

[0045] Starting with the connecting section between head piece 20 and housing halves 21a, 21b, the air column first encounters a partition 2a extending perpendicular to the longitudinal direction, which partition defines a first subsection 100a of bore 1. A change of direction of essentially 90 degrees occurs toward a second subsection 100b, which, viewed in the plane of housing half 21a, is defined by the front free end of partition 2a and the opposite side wall of housing half 21a. A change of direction of essentially 90 degrees occurs toward a third subsection 100c, which, viewed in the plane of housing half 21a, is defined by partition 2a and the opposite partition 2b.

[0046] A change in direction of essentially 90 degrees occurs toward a fourth subsection 100d, which, viewed in the plane of the housing half 21a, is delimited by the front free end of the partition wall 2b and the opposite side wall of the housing half 21a. A change in direction of essentially 90 degrees occurs toward a fifth subsection 100e, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2b and the opposite partition wall 2c.

[0047] A change of direction of essentially 90 degrees occurs toward a sixth subsection 100f, which, viewed in the plane of the housing half 21a, is delimited by the front free end of the partition wall 2c and the opposite side wall of the housing half 21a. A change of direction of essentially 90 degrees occurs toward a seventh subsection 100g, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2c and the opposite partition wall 2d.

[0048] A change in direction of essentially 90 degrees occurs toward an eighth subsection 100h, which, viewed in the plane of the housing half 21a, is delimited by the front free end of the partition wall 2d and the opposite side wall of the housing half 21a. A change in direction of essentially 90 degrees occurs toward a ninth subsection 100i, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2d and the opposite partition wall 2e.

[0049] A change of direction of essentially 90 degrees occurs, i.e., in the longitudinal direction of the main body 7, towards a tenth subsection 100j, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2f and the opposite side wall of the housing half 21a. This tenth subsection 100j has a taper 40q, which is formed by a projection of the side wall of the housing half 21a.

[0050] In the adjoining eleventh subsection 100k, which is formed between the front free end of the side wall 2f and the bottom 21e of the main body 7, there is a change in direction of substantially 180 degrees towards a twelfth subsection 100l, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2f and the opposite partition wall 2g.

[0051] A change in direction of essentially 90 degrees occurs toward a thirteenth subsection 100m, which, viewed in the plane of the housing half 21a, is delimited by the front free end of the partition wall 2g and the opposite partition wall 2e. A change in direction of essentially 90 degrees occurs toward a fourteenth subsection 100n, which, viewed in the plane of the housing half 21a, is delimited by the partition wall 2g and the opposite side wall of the housing half 21a.

[0052] The sound hole 21c of the recorder 30 thus formed is located at the end of the fourteenth section 100n and is formed in the bottom 21e of the main body 7.

[0053] How to Fig. 1 and Fig. 2, the cross-section of the scale 1, viewed in the plane of the casing half 21a, decreases substantially continuously from a connecting point between the headpiece 20 and the main body 7 and the sound hole 21c, which does not exclude the possibility that expansions or constrictions may be formed locally at any subsections, for example in the corner area 40f or in the area of ​​the recess 40l in the Fig. 2. In any case, the width or cross-sectional area of ​​the scale, averaged over the respective scale section 100a-100n, decreases continuously from a connection point between the headpiece 20 and the main body 7 and the sound hole 21c, as shown schematically in the Fig. 3, which shows three bore sections 1a to 1c with continuously decreasing width, viewed in the direction of the width of the main body 7, and decreasing cross-sectional area.

[0054] How to Fig. 1 and Fig. 2, various shapes can be provided in the partial sections 100a-100n of the scale 1 in order to suitably specify the acoustic properties of the recorder.

[0055] Thus, the two partition walls 2a, 2b are wedge-shaped overall. The top side 40c and the bottom side 40d of the partition wall 2a taper toward each other at a small, acute angle of approximately 10 degrees. Opposite, a U-shaped reversal area consisting of two corner regions 40b, 40f is formed in the side wall of the housing half 21a.

[0056] The top side 40g and the bottom side 40i of the partition wall 2b also extend toward each other in a wedge shape at a small, acute angle of approximately 10 degrees. However, a step 40h is formed in the bottom side 40i. Opposite, a U-shaped reversal area consisting of two corner areas 40e is formed in the side wall of the housing half 21a.

[0057] The top side 40k and bottom side 40m of the partition wall 2c extend essentially parallel to each other. Opposite, a U-shaped reversal region consisting of two corner regions 40j, 40l is formed in the side wall of the housing half 21a, with region 40l forming a recess in the top side 40n of the partition wall 2d, each with angular transition regions.

[0058] The top side 40n and the bottom side of the partition wall 2d also extend towards each other in a wedge shape, but at a much smaller acute angle in the range of about 4 degrees.

[0059] The partition wall 2f can also be wedge-shaped, tapering toward its front free end, but can also be designed with a front and rear side that run parallel to each other. This also applies to the partition walls 2d and 2g, as well as, in further embodiments, to any other pair of opposing partition walls.

[0060] According to the present invention, the acute angle enclosed by the opposing and wedge-shaped converging or diverging upper sides (front and back) may be in the range between -5 degrees and 10 degrees, more preferably in the range between -3 degrees and 5 degrees, and even more preferably in the range between -2 degrees and 3 degrees, but this is not intended to limit the present invention.

[0061] Opposite the front free end of the partition 2f, a generally U-shaped reversal area consisting of rounded regions 40r, 40s is formed in the base 21e of the housing half 21a. Opposite the front free end of the partition 2g, however, a flat underside of the partition 2e is provided. The last bore section 100n extends with a steadily decreasing width or cross-sectional area toward the sound hole 21c.

[0062] How to Fig. 1 and Fig. As can be seen directly from Figure 2, the aforementioned sections 100a-100n of the scale 1 are formed partly by angular corner areas, but also by stepped sections (see reference numerals 40h, 40l) or rounded sections (see reference numerals 40r, 40s). This is done in particular to adapt the acoustic properties of the instrument.

[0063] As will be readily apparent to the person skilled in the art, the sound hole 21c can be formed in other embodiments according to the invention, in particular with a stacking of scale sections in a direction perpendicular to the plane of the drawing of the Fig. 2, may also be formed at other positions of the main body 7, for example approximately centrally to the main body 7 and on its front side facing the audience.

[0064] Overall, at least one section with a non-linear scale guide is provided in the main body 7, with the scale guide being guided in a direction deviating from the longitudinal direction of the main body 7. This can be achieved, in particular, by jointly utilizing the front and rear sides of partition walls 2a-2g. The overall height of a recorder 30 according to the present invention, namely the distance between the wind channel entrance 11 and the underside of the instrument or the floor 21e of the main body 7, can be less than 800 mm due to the compaction of the scale, which allows for a seated playing position, as in the Fig. 5a shown.

[0065] As in the Fig. As shown in Figure 5a, pitch-setting sections 22a, 22b are provided in or on the main body 7. These are arranged and designed to enable ergonomically advantageous playing. In particular, excessive bending of the user's wrists when playing the instrument can be avoided for both playing hands according to the invention. Furthermore, the distances between the tone holes 22a, 22b can be specified due to a suitably selected scale compaction such that almost all tone holes 22a, 22b of a tone hole row can be reached within the user's normal finger spread, i.e., with the palm resting flat on the front of the main body 7.

[0066] If necessary, however, the tone holes 22a, 22b can optionally also be assigned pitch-setting sections 25a, 25b, which can be provided in sections without a non-linear scale guide. The pitch-setting sections 22a, 22b can have a first tone hole and / or a plurality of keys or pushers which, when actuated via the respective key mechanism 25a, 25b, if provided, act on a plurality of second tone holes (not shown). The second tone holes can be located further away from an ergonomic finger position, i.e., cannot be reached with the normally available finger spread, or can be provided in at least one section with a non-linear scale guide. A first tone hole can be formed in a section with a straight scale guide or in a section with a non-linear scale guide.The second tone holes can be formed, in particular, in sections with a non-linear scale. Such a first tone hole can be covered without a key or pusher, i.e., by means of a finger, but can also be covered by a key or pusher of the respective folding mechanism 25a, 25b. A plurality of keys or pushers can be arranged near the first tone hole, which together form an arrangement that is ergonomically favorable to play, with the keys or pushers then covering or uncovering the plurality of second tone holes via the respective folding mechanism 25a, 25b.

[0067] According to the invention, highly compact designs can be realized, for example with a box-shaped main body 7, as in the Fig. 5a, which can be played directly (without blowing tube), held vertically in front of the body without upper body torsion, played while sitting and also placed on the lap. Fig. 5a shows a relaxed right wrist 9 during playing. A clear view of the notation and the room, e.g., the orchestra, is thus possible according to the invention.

[0068] Due to the multiple use of the inner walls in the main body 7 and the free scale cross-sectional shape, a particularly good surface-to-weight ratio can be achieved according to the invention, which makes the instrument lighter and, above all, more compact, so that it can be handled, transported and set up considerably easier and safer.

[0069] This compact design allows for a single joining or plug-in connection between the head piece 20 and the main body 7, enabling consistently improved response even under changing climatic conditions. The material (e.g., plastic, wood, metal, or material combinations, etc.) and the manufacturing process used (e.g., subtractive, additive, casting, forming, etc.) are irrelevant.

[0070] The Fig. 7a and Fig. 7b show a recorder of a second embodiment according to the present invention in a sectional view in the longitudinal direction of the main body 21 and in a sectional view perpendicular to the longitudinal direction of the main body 21 in the lower region of the main body 21.

[0071] Deviating from the embodiment according to the Fig. 1 and Fig. 2, in which the sections 100a-100n of the scale 1 are predominantly formed by angular corner areas or also by stepped sections (cf. reference numerals 40h, 40l), in the second embodiment according to the Fig. 7a and Fig. 7b, care has been taken to avoid such angular corner areas as much as possible. This is done primarily to adapt the acoustic properties of the instrument.

[0072] In particular, the corner areas of the U-shaped reversal areas 100b, 100d, 100f, 100h, and 100k are each designed as rounded areas 40b' / 40f', 40c' / 40e', 40j' / 45, 40o' / 40p', and 40r / 40s, respectively. The front free ends of the partition walls 2f and 2g can also be designed as cylindrical sections 40v and 40w, respectively, in plan view, i.e., with a circular cross-section in plan view. Sections with a change in the direction of the oscillating air column of 90 degrees instead of 180 degrees are also bordered by rounded areas. Overall, this ensures that the cross-section of the scale 1, viewed in the plane of the case half 21a, decreases almost perfectly continuously from a connection point between the headpiece 20 and the main body 21 to the sound hole 21c. In any case, the width or diameter averaged over the respective scale section 100a-100n decreases.The cross-sectional area of ​​the scale decreases continuously from a connection point between the headpiece 20 and the main body 21 and the sound hole 21c as shown schematically in the . Fig. 7b, which shows three scale sections 1a to 1c with steadily decreasing width, viewed in the direction of the width of the main body 21, and decreasing cross-sectional area. This should not exclude the possibility that certain sections of the scale may also have a larger width, for example in the Fig. 7a the recess designated by the reference numeral 45, which is also expediently formed with rounded corners or transition areas to upstream or downstream sections.

[0073] As will be readily apparent to the person skilled in the art, the subdivision of the scale length into sections with non-rectilinear scale guidance chosen according to the invention results in widenings and narrowings of the scale length, the position and design of which can be specified as desired, in adaptation to the acoustic or ergonomic requirements of the respective musical instrument.
