Abstract: A musical accompaniment system is described including a fretted, stringed electric musical instrument, a floor unit, interface units and connecting cables. Designated frets of the instrument are divided into sections that output to a switching component that sends MIDI note # data to a synthesizer when strings of instrument contact designated fret sections. The floor unit includes actuators that output to the synthesizer when tapped by the user. The user taps on the actuators with his or her feet and thereby actuates accompaniment notes that are generated in the rhythms in which they are tapped. Accompaniment notes generated by the process are designated by notes and chords being fingered on the instrument. Methods are described that facilitate the actuating and generating of accompaniment notes in the musical style of traditional bass accompaniment through the use of the system.

Typically the melody note is identified and a spectrum of the accompaniment audio signal and is obtained, and one or more harmony notes are identified based on the melody note and the accompaniment spectrum. The melody, and accompaniment signals can be processed in real-time for combination with the harmony signal in an audio performance. In some examples, audio signals are processed and harmonies generated for subsequent performance based on, for example, MIDI files generated from the audio signals.

Abstract: A reproduction list PL1 and specified BPMs of pieces of music that are to be used to control the operation of replaying the pieces of music are prepared on the basis of their ordinary BPMs that indicate the tempos specified in advance for the respective pieces of music (and hence the reproduction speeds specified in advance by the audio data of the respective pieces of music) so that it is now possible to prepare with ease a reproduction list PL1 for replaying only pieces of music having the same tempo or specified BPMs for changing the tempo of each of the pieces of music to a desired one, according to the tempo of a piece of music. Thus, it is also possible to replay with ease each of the pieces of music with a desired tempo (or a reproduction speed) according to the reproduction list PL1 and the specified BPMs.
