Abstract: A musical-performance-information transmission method using a first instrument and a second instrument, wherein the first instrument produces sounds in accordance with a user's musical performance and generates musical-performance data in accordance with the produced sounds and the second instrument produces sounds by receiving the musical performance data via a communication means. In the musical-performance-information transmission method, a mixed-sound signal is generated in accordance with a mixture of sounds produced by the first instrument and sounds that are different from the sounds produced by the first instrument, a reference signal is generated in accordance with the sounds produced by the first instrument, and on the basis of the mixed-sound signal and the reference signal, the reference signal is removed from the mixed-sound signal, generating a separated signal, and sound is emitted on the basis of said separated signal.
