• the second key associated with second section data corresponding to a second section including at least one chorus part in a second piece of music, the second section data includes at least two notes and corresponds to a second period from a certain timing to another timing of the second piece of music, and
• the third key which is not associated with any section data corresponding to any section in both of the first piece of music and the second piece of music, and
• at least one processor electrically connected to the keyboard, wherein the at least one processor is configured to:
• display at least one identifier such that the first key and the second key are distinguishable from the third key;
• output the first section data as a musical sound when the first key is operated;
• and
• output the second section data as a musical sound when the second key is operated.

A method of a keyboard instrument, which includes:

• a first key specifying a first pitch and being associated with a first section data corresponding to a first section among a plurality of sections in a piece of music, the first section data including at least two notes and corresponding to a first period from a first timing to a second timing of the piece of music;
• a second key specifying a second pitch and being associated with a second section data corresponding to a second section following the first section among the plurality of sections in the piece of music, the second section data including at least two notes and corresponding to a second period from the second timing to a third timing of the piece of music;
• and a third key specifying a third pitch and being not associated with any section data corresponding to any section among the plurality of sections in the piece of music, the method comprising:
• displaying at least one identifier such that the first key and the second key are distinguishable from the third key;
• outputting the first section data as a musical sound when the first key is operated;
