Abstract
Abstract An electronic musical instrument includes first and second control switches for initiating chorus and verse break patterns in an automatic accompaniment arrangement. A chorus accompaniment pattern is automatically generated following the chorus break pattern and a verse accompaniment pattern is automatically generated following the verse break pattern, regardless of the pattern types generated prior to the breaks. The generation of breaks are inhibited during the last 1/4 interval of a bar and during the generation of the introduction and ending portions of the accompaniment arrangement.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
137 words
An electronic musical instrument comprising: memory means including a plurality of memory sections respectively storing a verse accompaniment pattern, a chorus accompaniment pattern, a verse break pattern and a chorus break pattern; first and second switch means operable by a performer for respectively generating first and second control signals; and control means coupled to said memory means for playing said verse and chorus accompaniment patterns and responsive to said first control signal for interrupting the playing of said verse or chorus accompaniment patterns with the playing of said chorus break pattern and thereafter automatically resuming playing of said chorus accompaniment pattern and responsive to said second control signal for interrupting the playing of said verse or chorus accompaniment patterns with the playing of said verse break pattern and thereafter automatically resuming playing of said verse accompaniment pattern.
