Abstract
CPU 11 reads from RAM 13 pitch information of each of musical notes composing the music, fingering information for playing the musical notes, and time information of the musical notes, thereby calculating a difficulty level of music. CPU 11 calculates a fingering difficulty level concerning fingering of playing adjacent musical notes based on the pitch information and fingering information, a rhythm difficulty level concerning musical-note duration and timing of key playing based on the time information, and a key difficulty level concerning a key of music based on the pitch information. Further, CPU 11 calculates the whole difficulty level of music based on the fingering difficulty level, rhythm difficulty level and key difficulty level.
