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.

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 relates to the development of a system for arranging Sheng sound tubes (Sheng tubes), which configures the tone positions of the sound tubes in a Sheng body so as to adjust the positions of finger holes in an alternating vertical arrangement, and introduces a new fingering system with increased touch points. The purpose of the invention is to enable a music player to play the traditional Yitong folk music and modern music styles in all dimensions of cultural diversity. These include folk, classical, jazz, modern and other international music genres, and have greater ease of use and versatility. The musical instrument provides half syllable notes (from the lowest A to the highest A) across a complete range of two octaves, which is characterized by a row Sheng 13 consisting of 13 pairs of row Sheng sound tubes (totally 26 sound tubes).

An input musical sound signal is input to band pass filters, and pass musical sound signals for each sound pitch are acquired. Total level ratios based on a total of levels of a sound pitch lower than those of the pass musical sound signals are calculated from the levels that are levels of the pass musical sound signals, and output coefficients are acquired on the basis of the total level ratios. Levels of octave musical sound signals acquired by converting the pass musical sound signals into sound pitches lower than those of the pass musical sound signals by one octave are multiplied by the output coefficients. In accordance with this, the octave musical sound signals of a low sound pitch can be extracted from among the octave musical sound signals.

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.
