Abstract: A keyboard instrument includes a processor and a keyboard including first, second and third keys. The first key is associated with first section data corresponding to a first section among a plurality of sections in a piece of music, includes at least two notes and corresponds to a first period of the piece of music. The second key is associated with second section data corresponding to a second section following the first section, includes at least two notes and corresponds to a second period of the piece of music. The third key is not associated with any section data. The processor displays an identifier such that the first and second keys are distinguishable from the third key, outputs the first section data as a musical sound when the first key is operated; and outputs the second section data as a musical sound when the second key is operated.
