摘要： A method and apparatus for composing and performing music on an electronic instrument in which individual chord progression chords can be triggered in real-time, while simultaneously making the individual notes of the chord, and/or possible scale and non-scale notes to play along with the chord, available for playing in separate fixed-locations on the instrument. The method of composition involves the designation of a chord progression section on the instrument, then assigning chords or individual chord notes to this chord progression section according to the defined customary scale or customary scale equivalent of a song key. Further, as each chord is played in the chord progression section, the individual notes of the currently triggered chords are simultaneously made available for playing in separate fixed locations on the instrument. Fundamental and alternate notes of each chord may be made available for playing in separate fixed locations for composing purposes. Possible scale and/or non-scale notes to play along with the currently triggered chord, may also be simultaneously made available for playing in separate fixed locations on the instrument. All composition data can be stored in memory or on a storage device, and can later be retrieved and performed by a user from a fixed location on the instrument. The composition data may also be performed from a reduced number of input controllers. Further, multiple instruments of the present invention can be utilized together to allow interaction among multiple users during composition and/or performance, with no knowledge of music theory required.

摘要： In a chord progression input/modification device, when a key and a single or two successive reference chords are designated by a user, available chords are acquired and displayed. Any one of the available chords can be used, in consonance with musical theory, to follow or substitute for the single reference chord, or to be inserted between the two reference chords for generating a modified chord progression. The chord progression modification device may be installed in an electronic musical instrument.

摘要： A device for detecting data of contents of accompaniment for use in an electronic musical instrument in which the detection of data representing contents of a bass accompaniment is effected independently of the detection of data representing contents of a chord accompaniment, by separately providing a first portion for indicating pitches composing a chord to be performed and a second portion for indicating the lowest pitch of a bass accompaniment pattern in a pitch indicating unit and detecting pitches indicated in the second portion. Thus, data representing contents of a bass accompaniment and data representing contents of a chord accompaniment can be separately detected, whereby the electronic musical instrument can perform a bass accompaniment independent of a chord accompaniment, and thus the variety of a performance can be increased. Further, in the device for detecting data of contents of an accompaniment, bit pattern data representing a chord to be performed as an accompaniment is generated by ORing data representing pitches of a predetermined octave-segment which correspond to pitches indicated by the pitch indicating unit in each octave-segment of the first portion, and the chord to be performed is detected by comparing the bit pattern data obtained as a result of the OR operation with bit pattern data corresponding to various chords stored in a memory, by sequentially shifting the bit pattern data obtained as the result of the OR operation, whereby even a chord in an inversion thereof can be easily and accurately detected.

摘要： An automatic accompaniment apparatus is adopted to a keyboard-type electronic musical instrument. Herein, the chord constituent notes and bass note of the subharmonic chord (or fractional chord) are detected and separated from the notes which are designated by the performer who depresses the keys of the keyboard. In response to certain chord note, particularly root of the chord, the desirable chord pattern (or chord type) is selected from the predetermined chord patterns memorized in a data table. This data table can be memorized with relatively small memory capacity. Thus, it is possible to accurately detect the subharmonic chord with small memory capacity. Then, the desirable subharmonic chord is automatically sounded as the accompaniment in accordance with the selected chord pattern and the detected bass note.

摘要： In an electronic musical instrument for automatically a adding duet note, an apparatus, which can reduce the capacity of a memory for storing data used as a basis for selecting a duet note to be added, is disclosed. A chord depressed at a keyboard is specified by a chord specifying means, and a depressed melody note (highest note) is detected by a note detection device. According to these notes, duet note data, which can be added, is read out from a chord-notes weighting information storage area on the basis of chord constituting notes, and another duet note data, which can be added, is read out from a note weighting information storage area according to a relative note data of the highest note relative to the root note of the chord. These readout duet note data are subjected to a calculation, thus selecting a duet note. Therefore, duet note data corresponding in numbers to chords and relative notes need only be stored in the memory, thus reducing the capacity of the duet note data memory.

摘要： Left- and right-hand keystroke windows X.sub.L and X.sub.H are decided in accordance with the positions of player's left and right hands pressing keys. When the number of pressed keys in either one of the windows X.sub.L and X.sub.H are larger than a predetermined value, that window is decided to be used as a chord identifying window, and on the basis of a combination of pressed keys in the chord identifying window, an accompaniment chord is decided for automatic accompaniment.

摘要： In order to play an automatic performance based on performance information which is stored in a storage device and the like in advance, an electronic musical instrument provides an automatic performance apparatus. The automatic performance apparatus is configured by a performance style designating portion, a storage portion, a read-out portion and an automatic performance portion. The performance style designating portion designates a desired performance style within a plurality of performance styles, each of which corresponds to a specific music genre such as rock music, jazz and pop music. The storage portion, such as a read-only memory, stores a plurality of chord progression patterns with respect to each of the performance styles. The read-out portion accesses the storage portion to automatically read out one of the chord progression patterns concerned with the desired performance style which is designated by the performance style designating portion. Herein, each of the chord progression patterns is given a specific priority, so that a certain chord progression pattern given a higher priority is selectively read out from the storage portion. Then, the automatic performance portion, which is configured by a tone generator and a sound system, plays an automatic performance in accordance with the chord progression pattern which is read from the storage portion by the read-out portion.

摘要： Melody note data and chord data are inputted to an automatic arrangement apparatus. When it is detected that a melody note is a nonharmonic note, the melody note is converted into a harmonic note, and an additional note (e.g., a countermelody note) is generated based on the converted harmonic note. An electronic musical instrument comprises such an automatic arrangement apparatus. Melody note data and chord data are inputted to the instrument according to a performance of a player. When it is detected that a melody note is a nonharmonic note, the melody note is converted into a harmonic note, an additional note is determined based on the converted harmonic note, and the additional note is produced as a tone in real time simultaneously with a performance tone.
