Abstract: There are provided an electronic musical apparatus, a storage medium storing a recording/reproduction program, and a recording/reproduction method capable of outputting a musical sound phrase and a rhythm phrase after the input musical sound phrase is output. In a case where a recording button is operated, a looper starts to record musical sounds. In this case, the musical sounds (that is, a musical sound phrase) that are being recorded are output from a speaker. Thereafter, in a case where a loop reproduction button is operated, the recording is stopped, and loop reproduction of the recorded musical sound phrase and a rhythm phrase is started. Consequently, it is possible to output musical sounds in which the musical sound phrase and the rhythm phrase are loop-reproduced after the input musical sound phrase is output.
