An electronic musical instrument is provided. The electronic musical instrument comprises performance operational elements including a first operational element and a second operational element. In response to a user operation of the first operational element during reproduction of the song data, the instrument receives first performance information including event information indicating an event other than a note event and event timing information indicating a timing of the user operation of the first operational element, and stores the first performance in a first region of the memory. In response to a user operation of the second operational element during reproduction of the song data, the instrument receives second performance information including note event information indicating a note event and note event timing information indicating a timing of the user operation of the second operational element, and changes the note event timing information into information indicating a timing among a plurality of timings determined in accordance with a set phonetic value, and stores the second performance information including the information indicating the timing among the plurality of timings in a second region of the memory. The first performance information and the second performance information are merged when no song data is reproduced after completion of the reproduction of the song data.
