Summary of the Invention

Problems to be Solved by the Invention

[0004] The sound produced by a reed formed of a resin material (hereinafter referred to as a resin-derived reed) tends to contain more high-order overtones than the sound produced by a reed formed of a plant material (plant-derived reed). Therefore, it is desired to realize various timbres with resin-derived reeds, including making the sound produced by resin-derived reeds closer to the sound produced by plant-derived reeds.

[0005] One object of the present invention is to realize various timbres with reeds formed other than plant materials.

Means for Solving the Problems

[0006] According to one embodiment, a lead is provided which includes a base portion and a vamp. The base portion has a flat portion and a heel at its end. The vamp extends from the base portion on the side opposite to the heel. The vamp includes a shape in which the tip of the vamp, when viewed from the flat portion, is inclined with respect to the flat portion.

[0007] In the aforementioned inclined shape, when the flat portion is facing upward and the vamp is viewed from the flat portion, the end of the tip may be located above the central portion.

[0008] The inclined shape may be symmetrical with respect to the center of the tip when the flat portion is facing upward and the vamp is viewed from the flat portion.

[0009] The inclined shape may be such that, when the vamp is viewed from the flat portion, the ends of the tip are connected by a curve.

[0010] The curve may have at least one inflection point.

[0011] The inclined shape may include a curve in which the uppermost part is convex upward when the flat surface is facing upward and the vamp is viewed from the flat surface.

[0012] When the tip is facing upward and the vamp is viewed from the flat portion, the lowest part of the tip may be located above the flat portion.

[0013] The base material and the vamp may contain a resin material.

[0014] According to one embodiment, a mouthpiece is provided that includes a table, side rails, and a tip rail. The side rails extend from the table. The tip rail extends from the side rails. The tip rail includes a shape that is inclined with respect to the table when viewed from the table.

[0015] The aforementioned inclined shape may result in the end of the tip rail being positioned above the central part when the table is facing upwards and the tip rail is viewed from the table.

[0016] The inclined shape may be symmetrical with respect to the center of the tip rail when the table is facing upwards and the tip rail is viewed from the table.

[0017] The inclined shape may be such that, when viewed from the table, the tip rail is connected to both ends by a curve.

[0018] The curve may have at least one inflection point.

[0019] The aforementioned inclined shape may include a curve in which the uppermost part is convex upward when the table is facing upward and the tip rail is viewed from the table.

[0020] According to one embodiment, a blowing section is provided which includes a reed and a mouthpiece. The reed has a tip. The mouthpiece has a tip rail. The tip and the tip rail have different first distances, which are the distances between them at a first position and second distances, which are the distances between them at a second position.

[0021] According to one embodiment, a blowing portion is provided that includes the lead described in any of the above and the mouthpiece described in any of the above. The flat portion is in contact with the table, and the distance between the tip and the tip rail at the first position may be different from the distance between them at the second position.

[0024] Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. The embodiments shown below are examples, and the present invention is not limited to these embodiments. In the drawings referenced in this embodiment, the same parts or parts having similar functions are denoted by the same or similar reference numerals (simply a number followed by A, B, etc.), and repeated descriptions may be omitted. In order to clarify the explanation, the drawings may be schematic in which dimensional ratios differ from actual ratios, or some parts of the configuration may be omitted from the drawings.

[0025] In one embodiment, the blowing section is, for example, the blowing section of a single reed used in a saxophone, and includes a reed and mouthpiece made of a resin material. The reed may be made of a material other than resin, such as an inorganic material such as metal or ceramics, but is made of a different material than the plant-derived reeds that have been commonly used in the past. Compared to conventional blowing sections, the shape of the opening (also called the tip opening) formed between the tip and the tip rail is different.

[0026] According to several embodiments described below, a different opening portion from the conventional one is achieved by making the shape of at least one of the tip and the tip rail different from the conventional one. The first embodiment describes an example in which the tip has a different shape from the conventional one. The second embodiment describes an example in which the tip rail has a different shape from the conventional one. The third embodiment describes an example in which both the tip and the tip rail have different shapes from the conventional one.

[0027] <First Embodiment> Figure 1 shows the blowing section in the first embodiment. Figure 1 shows an example of the blowing section viewed from the side. Figure 2 shows the reed and mouthpiece in the first embodiment. Figure 3 shows the tip (part) in the first embodiment viewed from the side (corresponding to the AR1 direction). Figure 4 shows the tip in the first embodiment viewed from the front end (corresponding to the AR2 direction). Figure 5 shows the tip rail in the first embodiment viewed from the front end (corresponding to the AR3 direction).

[0028] The blowing section 1 includes a reed 10, a mouthpiece 30, and a ligature 80. The ligature 80 is a component that secures the reed 10 and the mouthpiece 30. The mouthpiece 30 includes a table 351, side rails 353, a baffle 355, and a tip rail 300. The two side rails 353 extend from the table 351. The tip rail 300 extends from the two side rails 353. The tip rail 300 and the side rails 353 are positioned at the ends of the baffle 355.

[0029] With the table 351 facing upwards, and viewing the mouthpiece 30 parallel to the surface of the table 351 and from the tip rail 300 side (corresponding to the AR3 direction in Figure 2), the tip of the tip rail 300 forms a line substantially parallel to the plane formed by the table 351, as shown in Figure 5. The tip rail 300 is substantially planar and, relative to the surface of the table 351, is inclined in the same direction as the inclination of the side rail 353. That is, when viewing the mouthpiece 30 from the side, as in Figure 1, the surface of the tip rail 300 is inclined relative to the surface of the table 351.

[0030] On the other hand, as shown in Figure 5, when viewing the mouthpiece 30, it can also be said that the surface of the tip rail 300 (especially the tip) does not have a portion that is substantially inclined with respect to the surface of the table 351. When the surface of the tip rail 300 is parallel to the surface of the tip rail 300 and the mouthpiece 30 is viewed from the tip rail 300 side (corresponding to the D1 direction in Figure 1), the tip portion of the tip rail 300 is perceived as a straight line parallel to the surface of the table 351.

[0031] The reed 10 includes a base portion 150 and a vamp 153. The base portion 150 includes a flat portion 151 and a heel 157. The flat portion 151 is located on at least one face of the base portion 150. In this example, the flat portion 151 corresponds to at least a portion of the plane that contacts the table 351 when attached to the mouthpiece 30. The vamp 153 extends from the base portion 150 on the side opposite to the heel 157. That is, the vamp 153 is located at one end of the longitudinal direction of the reed 10 and is a portion that gradually decreases in thickness towards the end. The tip of the vamp 153 is the tip 100.

[0032] When the flat section 151 is facing upwards and the vamp 153 is viewed from the side (corresponding to the AR1 direction in Figure 2), as shown in Figure 3, a portion of the vamp 153 (particularly both ends in the width direction) has a shape that is bent upwards. Due to this shape, as shown in Figure 4, the ends 100e1 and 100e2 of the tip 100 are located above the central part 100c of the tip 100. The dashed lines shown in Figure 2 for the portion of the vamp 153 correspond to the position where the upper surface of the vamp 153 is no longer parallel to the flat section 151 due to the bent shape.

[0033] When the flat section 151 is facing upwards, and the vamp 153 is viewed from the flat section 151 (corresponding to the AR2 direction in Figure 2), the vamp 153 is viewed, as shown in Figure 4, and the tip 100 has a shape that is inclined relative to the flat section 151. When the tip 100 is viewed as shown in Figure 4, the tip 100 in this example has the following characteristics.

[0034] Tip 100 is connected to end 100e1 and end 100e2 by a curve. Ends 100e1 and 100e2 of tip 100 are located above the central part 100c of tip 100. Tip 100 is symmetrical with respect to the central part 100c. The lowest central part 100c of tip 100 is located above the flat part 151. The lowest part of tip 100 (central part 100c) may be located below the flat part 151, or the highest part (ends 100e1 and 100e2) may be located below the flat part 151. The above is a description of the configuration of the blowing section 1.

[0035] Next, we will explain how sound is produced when using the blowing section 1 described above. First, we will explain the situation when the reed 10 vibrates.

[0036] Figure 6 illustrates the change in the positional relationship between the tip rail and the tip when the reed is vibrating in the first embodiment. The positional relationship between the tip rail 300 and the tip 100 shown in Figure 6 is when viewed from the tip end of the blowing section 1 (corresponding to the D1 direction in Figure 1). The D1 direction is the direction along the surface of the tip rail 300, and is the direction in which the tip rail 300A appears as a straight line. The space between the tip rail 300 and the tip 100 corresponds to the opening (tip opening). Figure 6 shows the positional relationship between the tip 100 and the tip rail 300 at five timings ((1) to (5)) when the reed 10 is vibrating.

[0037] At timing (1), the opening is in the open state (OPEN), and at timing (5), the opening is in the closed state (CLOSE). The state shown at timing (1) may not be the state in which the opening is most open. In the initial state when the reed 10 is attached to the mouthpiece 30, it may be the state at timing (1), or it may be the state at other timings such as timing (2). The same applies to Figures 8 and 14 described below as well as Figure 6.

[0038] As in the example in timing (1), the tip 100 has the largest distance dc (first distance) to the tip rail 300 at the central part 100c (first position), and the distance de (second distance) to the tip rail 300 near the ends 100e1 and 100e2 (second position) is smaller than distance dc. In other words, there are two positions where the distance between the tip 100 and the tip rail 300 is different from each other.

[0039] With this configuration, as shown in Figure 6, the tip 100 and the tip rail 300 first come into contact at the points where they are close together (ends 100e1 and 100e2 in this example). Then, the tip 100A in the central section 100c gradually closes, and the tip 100 and the tip rail 300 finally come into contact at the central section 100c.

[0040] Therefore, the smaller the area of ​​the opening (hereinafter referred to as the opening cross-sectional area), the smaller the time change (time derivative) of the opening cross-sectional area per unit time. In other words, the smaller the maximum distance between tip 100 and tip rail 300, the smaller the time change becomes.

[0041] For comparison, we will also explain the positional relationship between the tip rail and the tip in the case of a conventional flat-shaped resin lead.

[0042] Figure 7 illustrates the shape of a conventional tip. Figure 7 shows an example of a conventional resin-derived lead 10Z viewed from the heel 157Z side with the flat portion 151Z facing upwards, in the same orientation as in Figure 4. As shown in Figure 7, the tip 100Z lies on the same plane as the flat portion 151Z. Thus, in the conventional resin-derived lead 10Z, the flat shape extends to the tip 100Z portion.

[0043] Figure 8 illustrates the change in the positional relationship between the tip rail and the tip when a conventional resin-based lead is vibrating. As shown in Figure 8, the distance between the tip 100Z and the tip rail 300 in a conventional lead 10Z is substantially the same at all positions. Therefore, during the vibration of the lead 10Z, the situation in which the tip 100Z and the tip rail 300 partially contact rarely occurs. Consequently, the time change of the opening cross-sectional area per unit time when the opening cross-sectional area is reduced is larger than in the example in Figure 6. The time change of the opening cross-sectional area will be further explained by comparing the situation in Figure 6 and the situation in Figure 8.

[0044] Figure 9 shows the change in the opening cross-sectional area when the reed is vibrating. In Figure 9, waveform PC (solid line) shows the change in the opening cross-sectional area when reed 10 vibrates, and waveform CC (dashed line) shows the change in the opening cross-sectional area when reed 10Z vibrates. Figure 9 shows only one opening and closing. Waveform PC changes more gradually than waveform CC in the part close to the closed state (CLOSE). This gradual change indicates that the higher-order harmonic components in waveform PC are attenuated compared to waveform CC. Since the change in the opening cross-sectional area corresponds to the sound generated inside the blowing section 1, the blowing section 1 using reed 10 produces fewer higher-order harmonic components and a softer sound than the blowing section using reed 10Z.

[0045] Here, conventional plant-derived reeds generally have the same flat plate shape as reed 10Z. It was thought that when a plant-derived reed vibrates, the relationship between the tip and the tip rail changes as shown in Figure 8. In reality, the inventors' investigation confirmed that when the reed starts vibrating at timing (1) in Figure 8, both ends of the tip deform during the vibration, causing the ends of the tip to move closer to the tip rail. That is, when the reed starts vibrating, the positional relationship changes from the positional relationship at timing (1) shown in Figure 8 to the positional relationship at timing (1) shown in Figure 6, and it was confirmed that the change in the opening cross-sectional area corresponds to the change shown in Figure 6.

[0046] Thus, in the case of plant-derived reeds, even with the same shape as reed 10Z, it was confirmed that they did not vibrate as shown in Figure 8, but rather approached the vibration shown in Figure 6 during vibration. This phenomenon is thought to occur because the orientation of the plant fibers contained in the reed material causes anisotropy in mechanical properties such as Young's modulus.

[0047] It is not easy to form a reed with mechanical properties similar to a plant-derived reed using a different material. On the other hand, according to the blowing section 1 in one embodiment, even if a reed made of a material with non-anisotropic mechanical properties is used, the shape can be set so that the distance between the tip 100 and the tip rail 300 differs depending on the position in the width direction, thereby suppressing higher harmonic components and bringing the sound closer to that of a plant-derived reed. Furthermore, by setting various relationships between the distance between the tip 100 and the tip rail 300 and their positions in the width direction, the higher harmonic components can be adjusted. As a result, a variety of timbres can be achieved.

[0048] <Second Embodiment> Figure 10 shows the blowing section in the second embodiment. Figure 11 shows the reed and mouthpiece in the second embodiment. Figure 12 shows the tip rail in the second embodiment viewed from the side (corresponding to the AR4 direction). Figure 13 shows the tip rail in the second embodiment viewed from the rear end (corresponding to the AR5 direction).

[0049] The blowing section 1A includes a reed 10A, a mouthpiece 30A, and a ligature 80A. Ligature 80A is the same as ligature 80. Reed 10A includes a base portion 150A and a vamp 153A. Reed 10A is the same as the conventional reed 10Z described above. That is, when the flat portion 151A is facing upwards and the vamp 153A is viewed from the flat portion 151A, the tip 100A at the end of the vamp 153A is formed flat with respect to the flat portion 151A, similar to the tip 100Z shown in Figure 7. Therefore, the surface of reed 10A on the flat portion 151A side forms a flat surface from the heel 157A to the tip 100A.

[0050] The mouthpiece 30A includes a table 351A, a side rail 353A, a baffle 355A, and a tip rail 300A. When the table 351A is facing upwards and the mouthpiece 30A is viewed from the side (corresponding to the AR4 direction in Figure 11), as shown in Figure 12, a portion of the surface of the tip rail 300A and a portion of the surface of the side rail 353A (particularly both ends in the width direction) are bent upwards. Due to this shape, as shown in Figure 13, the ends 300Ae1 and 300Ae2 of the tip rail 300A are located above the central portion 300Ac of the tip rail 300A.

[0051] When the table 351A is facing upwards, and the tip rail 300A is viewed from the table 351A (corresponding to the AR5 direction in Figure 11), the tip rail 300A includes a shape that is inclined relative to the table 351A, as shown in Figure 13. The tip rail 300A in this example has the following characteristics.

[0052] The ends 300Ae1 and 300Ae2 of the tip rail 300A are connected by a curve. The ends 300Ae1 and 300Ae2 of the tip rail 300A are located above the central part 300Ac of the tip rail 300A. The tip rail 300A is symmetrical with respect to the central part 300Ac.

[0053] Next, we will explain the pronunciation when using the aforementioned blowing unit 1A.

[0054] Figure 14 illustrates the change in the positional relationship between the tip rail and the tip when the reed is vibrating in the second embodiment. The positional relationship between the tip rail 300A and the tip 100A shown in Figure 14 is as seen from the tip end to the blowing section 1A in Figure 10 (corresponding to the D2 direction in Figure 10). The D2 direction is along the planar section 151A, and is the direction in which the tip 100A appears as a straight line.

[0055] In the blowing section 1A, as in the example in timing (1), the distance dc from the tip 100A to the tip rail 300A is largest at the central section 300Ac, while the distance de from the tip rail 300A near the ends 300Ae1 and 300Ae2 is smaller than the distance dc. In other words, there are two positions where the distance between the tip 100A and the tip rail 300A is different from each other.

[0056] With this configuration, as shown in Figure 14, the tip 100A and the tip rail 300A first come into contact in the area where they are close together (in this example, the ends 300Ae1 and 300Ae2). Then, the tip 100A gradually closes in the central part 300Ac, and the tip 100A and the tip rail 300A finally come into contact in the central part 300Ac.

[0057] Therefore, the smaller the opening cross-sectional area, the smaller the time change of the opening cross-sectional area per unit time. In other words, the smaller the maximum distance between tip 100A and tip rail 300A, the smaller the time change becomes. Consequently, in blowing section 1A, as with blowing section 1, it is possible to produce a softer sound with fewer higher-order harmonic components than in blowing section using reed 10Z.

[0058] <Third Embodiment> Figure 15 shows the blowing section in the third embodiment. The blowing section 1B includes a reed 10B, a mouthpiece 30B, and a ligature 80B. The ligature 80B is the same as the ligature 80. The reed 10B is generally the same as the reed 10, and the curvature of the tip 100B is less than that of the tip 100. The mouthpiece 30B is generally the same as the mouthpiece 30A, and the curvature of the surface of the tip rail 300B is less than that of the surface of the tip rail 300A.

[0059] Figure 16 is a diagram illustrating the relationship between the tip rail and the tip in the third embodiment. The positional relationship between the tip rail 300B and the tip 100B shown in Figure 16 is as seen from the tip end to the blowing section 1B in Figure 15 (corresponding to the D3 direction in Figure 15).

[0060] In the blowing section 1B, the distance dc from the tip rail 300B to the tip rail 300B is largest at the central part 100Bc of the tip rail 100B (the central part 300Bc of the tip rail 300B), and the distance de from the tip rail 300B near the ends 100Be1 and 100Be2 of the tip rail 300B is smaller than the distance dc. In other words, there are two positions where the distance between the tip rail 100B and the tip rail 300B is different from each other.

[0061] Because the tip 100B and the tip rail 300B have this positional relationship, the smaller the opening cross-sectional area, the smaller the time change of the opening cross-sectional area per unit time. In other words, the smaller the maximum distance between the tip 100B and the tip rail 300B, the smaller the time change becomes. Therefore, in the blowing section 1B, as with the blowing section 1, it is possible to produce a softer sound with fewer higher-order harmonic components than in the blowing section using the reed 10Z.

[0062] <Variation> This disclosure is not limited to the embodiments described above, but includes a variety of other modifications. For example, the embodiments described above are described in detail for the purpose of illustrating this disclosure and are not necessarily limited to having all the configurations described. That is, some of the configurations of each embodiment may be replaced with other configurations or deleted. Some modifications are described below. In the following description, the first embodiment may be described as a modified example, but it may also be applied as a modified example of the second or third embodiment.

[0063] (1) In the blowing section 1 with the reed 10 attached to the mouthpiece 30, if there are two positions where the distance between the tip 100 and the tip rail 300 is different, the relationship between the tip rail 300 and the tip 100 is not limited to the examples in the first to third embodiments, but can be in various ways. Several variations of the relationship between the tip rail 300 and the tip 100 will be described below.

[0064] Figures 17 to 24 illustrate the relationship between the tip rail and the tip in modified examples. In each figure, the diagram corresponds to timing (1) shown in Figure 6. The tip rails 300C to 300K shown below are all the same as tip rail 300.

[0065] The tip 100C of the blowing section 1C shown in Figure 17 includes a central part 100Cc closest to the tip rail 300C, and ends 100Ce1 ​​and 100Ce2 furthest from the tip rail 300C. In other words, the relationship between the central part and the ends of the tip 100C is reversed compared to the tip 100 in the first embodiment. Thus, the part with the smallest distance between the tip 100 and the tip rail 300 does not have to be the end of the tip, and the part with the largest distance does not have to be the central part of the tip 100.

[0066] The tip 100D of the blowing section 1D shown in Figure 18 includes the end 100De1 closest to the tip rail 300D and the end 100De2 furthest from the tip rail 300D. Like tip 100D, the tip does not have to be symmetrical with respect to the center, and one of the ends (end 100De1 in this example) may be located above the center. Furthermore, tip 100D is connected to end 100De1 and end 100De2 by a straight line. Thus, tip 100 is not limited to being connected to both ends by a curve; it may also be connected by a straight line, or by a combination of a straight line and a curve.

[0067] The tip 100E of the blowing section 1E shown in Figure 19 includes the ends 100Ee1 and 100Ee2 closest to the tip rail 300E, and the central part 100Ec furthest from the tip rail 300E. Near the central part 100Ec, the distance from the tip rail 300E does not change, and the tip 100E and the tip rail 300E are parallel. The ends 100Ee1 and 100Ee2 are connected by three straight lines. An angle CN1 is formed between the central part 100Ec and the end 100Ee1, and an angle CN2 is formed between the central part 100Ec and the end 100Ee2.

[0068] The tip 100F of the blowing section 1F shown in Figure 20 includes a central section 100Fc closest to the tip rail 300F, and ends 100Fe1 and 100Fe2 furthest from the tip rail 300F. Near the central section 100Fc, the distance from the tip rail 300F does not change, and the tip 100F and the tip rail 300F are parallel. Similar to the tip 100E, the ends 100Fe1 and 100Fe2 of the tip 100F are connected by three straight lines. An angle CN3 is formed between the central section 100Fc and end 100Fe1, and an angle CN4 is formed between the central section 100Fc and end 100Fe2.

[0069] The tip 100G of the blowing section 1G shown in Figure 21 includes a central section 100Gc closest to the tip rail 300G, and ends 100Ge1 and 100Ge2 furthest from the tip rail 300G. Ends 100Ge1 and 100Ge2 are connected by two straight lines. The central section 100Gc forms the corner connecting the two straight lines.

[0070] The tip 100H of the blowing section 1H shown in Figure 22 includes the ends 100He1 and 100He2 closest to the tip rail 300H, and the central part 100Hc furthest from the tip rail 300. Similar to tip 100G, tip 100H is connected to ends 100He1 and 100He2 by two straight lines. The central part 100Hc forms the corner where the two straight lines connect.

[0071] Tip 100 may have a shape in which both ends are connected by a line made up of multiple straight lines, as shown in Figures 19 to 22, such as Tip 100E, 100F, 100G, and 100H. Tip 100 may also have a shape in which both ends are connected by a line made up of a combination of straight lines and curves.

[0072] The tip 100J of the blowing section 1J shown in Figure 23 includes the ends 100Je1 and 100Je2 closest to the tip rail 300J, and the central part 100Jc furthest from the tip rail 300J. The ends 100Je1 and 100Je2 are connected by a curve. An inflection point BP1 is formed between the central part 100Jc and the end 100Je1, and an inflection point BP2 is formed between the central part 100Jc and the end 100Je2.

[0073] The tip 100K of the blowing section 1K shown in Figure 24 includes a central section 100Kc closest to the tip rail 300K, and ends 100Ke1 and 100Ke2 furthest from the tip rail 300K. The ends 100Ke1 and 100Ke2 are connected by a curve. An inflection point BP3 is formed between the central section 100Kc and end 100Ke1, and an inflection point BP4 is formed between the central section 100Kc and end 100Ke2.

[0074] Tip 100 may have multiple inflection points in the curve connecting its two ends, as shown in Figures 23 and 24. It may also have only one inflection point. In this case, it is preferable that the portion located above tips 100J and 100K, i.e., the portion close to tip rail 300J, is a curve that is convex upwards.

[0075] For example, in the case of tip 100J shown in Figure 23, the curves near end 100Je1 and end 100Je2, that is, the curves on the end side of the inflection points BP1 and BP2, are convex upward (towards tip rail 300J). With this configuration, after the ends 100Je1 and 100Je2 of tip 100J come into contact with the tip rail 300J, tip 100J can slide more easily on the tip rail 300J.

[0076] In the case of tip 100K shown in Figure 24, the curve near the central part 100Kc, that is, the curve between inflection points BP3 and BP4, is convex upward (towards tip rail 300K). This configuration allows for gentle contact when tip 100K and tip rail 300K come into contact.

[0077] (2) In Modification Example (1), several examples relating to the shape of the tip 100 are described, but the tip 100 and the tip rail 300 may be interchanged, as in the relationship between the first and second embodiments. That is, a modification of the shape of the tip 100 can also be applied as a modification relating to the shape of the tip rail 300. A modification of the shape of the tip 100 can also be applied as a modification relating to the shapes of both the tip 100 and the tip rail 300, as in the relationship between the first and third embodiments.

[0078] (3) The blowing section 1 is not limited to being detachable from the main body of the wind instrument, but may also be configured not to be detachable from the main body of the wind instrument.

[0079] (4) The blowing section 1 may be used in electronic wind instruments, etc.

[0080] (5) The blowing section 1 may be formed by integrally creating the reed 10 and the mouthpiece 30. In this case, the ligature 80 is not required. [Explanation of symbols]
