Abstract: 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.

Abstract: A method of adapting a keyboard musical instrument to produce sound in response to the activation of keys included in a typewriter keyboard is disclosed. A standard typewriter keyboard is coupled to a conventional electronic sound generation platform in lieu of or in addition to a standard piano keyboard. Musical chords are assigned to keys typically operated by a user's left hand. Forty-eight chords are producible by multiplexing each of 24 keys located on the left side of the keyboard to produce one of two possible chords. The selection of the one of two possible chords is performed in response to manipulation of the left shift key. Melody notes are assigned to keys typically operated by a user's right hand. Thirty-one melody notes are assigned to 26 keys located on the right side of the typewriter keyboard. Thus, five of the 26 keys are multiplexed to produce one of two possible melody notes, selectable through operation of the right shift key.

Abstract: Root and type of a chord are discriminated at discriminators in accordance with the operation status on a fingerboard.

An automatic accompaniment or a manual play is performed according to the discriminated chord obtained at chord discriminating device.

Abstract: For use in or with an electronic musical instrument, an automatic accompaniment apparatus has a keyboard, a chord detector detecting a chord played on the keyboard, a judging circuit judging chord establishment of the detector chord, and a chord accompaniment tone generator producing, in accordance with an automatic rhythm pattern, chord tones for the detected chord when chord establishment is judged. This apparatus further comprises a tone generator for producing the tones of arbitrarily depressed keys when chord establishment is not judged. Thus, automatic accompaniment and manual performance are automatically selected according to the state of key depressions.

Abstract: An electronic musical instrument having automatic bass chord accompaniment performance in which bass tones are generated in different manners depending on the state of the keyboards of the device. Chord and bass notes are selected using lower and pedal keyboards, respectively. The chord type and root note are identified from the depressed keys of the keyboards. The bass tone is generated with consideration of whether the identified root note coincides with the selected bass note. In the situation where the root note coincides with the bass note, a bass tone is generated based on a stored predetermined bass pattern corresponding to the particular chord type and root note identified. In the situation where the root note does not coincide with the bass note, or if a chord type has not been identified, a bass tone is generated based on the depressed bass note key.
