Abstract: A musical performance apparatus including at least one processor configured to: determine any phrase as a first phrase that is to be a performance target performed by a user from among a plurality of phrases included in a musical piece, and determine a set of phrases from the first phrase to a second phrase to be phrases that are to be the performance target performed by the user according to operation by the user in order to select the second phrase from the plurality of phrases.

Abstract: In an electronic device for an electronic musical instrument, a determination grace period during which a plurality of operations on the electronic musical instrument by a user are determined to be simultaneously performed for the first section is set based on the data included in a first section of the song having a plurality of sections. Automatic accompaniment is advanced from the first section to the next second section when a user operation of the electronic musical instrument is detected outside of the determination grace period for the first section during the playback of the first section of the accompaniment, and automatic accompaniment is not advanced from the first section to the second section when the user operation of the electronic musical instrument is detected within the determination grace period for the first section during the playback of the first section of the accompaniment.

Abstract: An electronic musical instrument includes a memory storing a musical piece data that includes a first note or chord to be played by the performer at a first timing, a second note or chord to be played by the performer at a second timing, and a third note or chord to be played by the performer at a third timing and a processor that determines a target melodic interval direction from the first note or chord to the second note or chord, and that causes an automatic accompaniment to output from the second timing to a point in time immediately prior to the third timing even if the performer performs a wrong note as the second note as long as a melodic interval direction actually performed by the performer matches the target melodic interval direction.

Abstract: The present invention receives sound wave data from a sound inputted into a microphone and samples the sound wave data received using a CPU to obtain sampled data as a digitized tone data, which is then stored in a sampling memory. The CPU performs auto-play of a sound using the digitized tone data sampled by the sampling and stored in the sampling memory. Thus, a result of the sampling is automatically provided to the user after the sampling takes place and the user can intuitively understand what can be done through sampling.
