This set provides an efficient scale sight-reading learning tool for piano beginners, allowing them to easily learn how to read musical scales on the staff and the correct key placement, even without a piano. [Solution] The scale reading learning set 1, which has a main body with four octaves of musical staff lines, is equipped with rotatably supported sheet winding knobs 4 and 5, and a transparent sheet for writing musical notes 6 that is stretched over the sheet winding knobs 4 and 5 via a transparent sheet for writing musical notes retraction hole 7. By rotating the sheet winding knobs 4 and 5, the musical note marks written on the transparent sheet for writing musical notes 6 move along the musical staff lines. This makes the scale reading learning set 1 compact, limits the range of the musical staff lines to four octaves, and improves the efficiency of learning to read musical notes by allowing the transparent sheet for writing musical notes 6 to move smoothly from side to side and allowing the written musical notes to be read immediately.

The present invention relates to a symmetrical dodecaphonic harmony notation system for 12 ET based music, abbreviated as SymD notation. One of the most predominant characteristics of SymD notation is a staff of 5 lines arranged symmetrically with 8 space settings between and beside the lines for all 12 semitones and its octave in a 12 ET scale. The staff serves as a visual reference for intervallic harmony relationships in sonority and melody progressions in 12 ET music.

A method for encoding musical information includes accessing a database storing musical information for a song in the form of a string of notes and text. The text is divisible into a string of graphemes, each grapheme corresponding to a note in the string of notes. A reference note is selected from the string of notes. Each note in the string of notes is associated with a degree selected from among 12 degrees in an octave, relative to a reference degree corresponding to the reference note. Twelve different colors are associated with the 12 degrees. The different colors are selected according to a degree-color function linking each degree to a respective color. The notes in the string are divided into different groups corresponding to different musical octaves. One or more specific printing attributes are associated with each musical octave. For each grapheme, data is stored indicating the color associated with the degree of the note corresponding to the grapheme and one or more specific printing attributes associated with the musical octave to which the note corresponding to the grapheme belongs.

An electronic musical instrument played by fingered input on an array of playable touch regions (e.g. virtual or physical keys), and a secondary user-manipulation (e.g. tilt) of separate and distinct character from the fingered input and produces a responsive output signal of linear character. At quantized intervals, whose timing is independent of user-activation of the regions, the instrument samples the responsive signal for an instantaneous value, converts that value into converted pitch class and octave values, and calculates an output octave based on a combination of the converted octave and a region octave of an active region, whose pitch is outputted at the calculated octave. A unique hold mode activates and deactivates any region by sequential touches thereof. The regions can be transposed via a base value of a chosen region in a reset transpose mode, or by current value of the chosen regions in an iterative transpose mode.

The present invention provides an automatic arrangement method, an automatic arrangement device, and a computer program product, which can produce arrangement data that is easy to play and has a reduced number of simultaneously sounding notes from musical piece data. The present invention determines an outer sound symbol, and the outer sound symbol is the highest in pitch among notes that have substantially the same sounding start time in a melody part obtained from the musical piece data. A melody part from which an inner sound symbol is deleted is produced, and the inner sound symbol starts to sound during the sounding period of the outer sound symbol and is low in pitch. For each pitch range in which the pitch range of one octave is staggered by one semitone, a candidate accompaniment part in which the root notes of each chord of the chord data of the musical piece data are arranged to sound at their sounding timing is produced, and an accompaniment part is selected therefrom. The arrangement data obtained from the melody part and the accompaniment part can be set as arrangement data that is easy to play and has a reduced number of simultaneously sounding notes.

[Solution] When the intensity index value Vr, which corresponds to the first exhalation intensity V1 based on the air velocity of the exhaled air blown into the upper inlet 310 and the second exhalation intensity V2 based on the air velocity of the exhaled air blown into the lower inlet 311 located adjacent to the upper inlet 310, is greater than or equal to the first pitch change threshold Tcrd, the sound production of a musical tone based on a different pitch that is one octave higher than the key pitch is initiated. This makes it easy to switch to a musical tone based on a different pitch by adjusting the air velocity of the exhaled air blown into the upper inlet 310 and the lower inlet 311 by the performer, similar to how it is done with actual wind instruments such as a flute.
