A CPU 21 executes a program stored in an external storage device 25 to convert original music data including a series of note information in accordance with a fundamental tone for a first musical instrument into new music data including a series of note information in accordance with a fundamental tone for a second musical instrument having a fundamental tone different from that for the first musical instrument. In this case, the transposition is made by the difference between the fundamental tone for the first musical instrument included in the original music data and the fundamental tone for the second musical instrument. Further, the CPU 21 octave-shifts the note information in the new music data so as to be within the performable tone range for the second musical instrument, and octave-shifts the note information in the new music data so as to be within the tone range suitable for the performance of the second musical instrument. Then, the CPU 21 displays on a display device 12 notes and fingering based upon the note information in the new music data.
