Abstract
In a method for providing musical accompaniment in response to the playing of an accompaniment-type musical instrument, accompaniment chord voicing is randomly selected from a pluraltiy of stored possibilities and the chord is sounded according to the selected voicing. In a preferred embodiment, the voicings may be stored separately from rhythm information according to which the chord is to be sounded, and the selection of chord voicings is constrained by a pre-selected range of chord tones. In another method for providing musical accompaniment having at least one stored melodic figure, melodic information is represented as a plurality of tokens independent of chord type and the tokens are subsequently converted to note parameters appropriate for a preselected chord type. The tokens are preferably related to the scale functions of the melodic information and may also contain information for each of a plurality of chord sub-types.
