Abstract

An electronic musical instrument internally stores automatic performance data. The electronic musical instrument reads automatic performance data to perform an automatic performance, while incrementing melody tone pitch data contained in the automatic performance data. The electronic musical instrument obtains a valve state signal from an operated state of a plurality of performance operators. The electronic musical instrument automatically generates pitch data corresponding to a pitch of a voice on the basis of the melody tone pitch data. The electronic musical instrument extracts tone pitch candidates on the basis of the valve state signal, and determines a tone pitch in accordance with the automatically generated pitch data and the tone pitch candidates. The timing at which the determined tone pitch matches the melody tone pitch data is regarded as the timing to increment the melody tone pitch data.

Dependent claims

A musical instrument having a plurality of performance operators and an oral input section for inputting a signal containing pitch information related to a pitch generated by a mouth, the musical instrument comprising:

an ancillary performance section for sequentially outputting first performance data representative of a tone pitch of a musical tone;
a pitch data generating section for generating pitch data corresponding to a tone pitch represented by the first performance data sequentially output from the ancillary performance section;
and
a tone pitch determination section for determining in a first playing mode a tone pitch of a musical tone that should be generated solely on the basis of the pitch represented by the generated pitch data and a combination of operation of the plurality of performance operators, regardless of any signal input to the oral input section.

An electronic musical apparatus comprising:

an oral input section for inputting a voice signal generated by a mouth:
a voice signal input circuit coupled to receive the voice signal from the oral input section, wherein the voice signal input circuit includes a level sensing circuit for sensing an input tone volume level of the oral input signal;
a plurality of performance operators;
a switching circuit coupled to the performance operators for outputting a performance operator state signal in response to operation of the performance operators;
a memory for storing performance data representative of a musical tone, wherein said performance data includes tone pitch data corresponding to the musical tone;
a processing section coupled to receive the input tone volume level, the performance operator state signal, and the performance data, and to selectively generate an output tone pitch signal,
wherein the processing section includes:
a performance data reading and processing section that reads the performance data, while incrementing the tone pitch data contained in the performance data;
means for generating voice pitch data corresponding to the tone pitch data from the performance data stored in the memory;
a tone pitch candidate extraction processing section that extracts tone pitch candidates from the performance operator state signal;
and
