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.

A music difficulty level calculating apparatus comprising:
- a storing unit for storing musical-tone data, wherein the musical-tone data includes pitch information of each of musical notes composing music, fingering information for playing the musical notes, and time information of each of the musical notes;
- a separate difficulty level calculating unit for calculating separate difficulty levels on plural elements required for playing music respectively, based on either one of the pitch information, the fingering information and the time information stored in the storing unit;
- and
- a whole difficulty level calculating unit for calculating a whole difficulty level of music based on the separate difficulty levels calculated by the separate difficulty level calculating unit.
In a music difficulty level calculating apparatus provided with a storing unit, which stores musical-tone data including pitch information of each of musical notes composing music, fingering information for playing the musical notes, and time information of each of the musical notes, a method of calculating a music difficulty level, comprising:
- a separate difficulty level calculating step of calculating separate difficulty levels on plural elements required for playing music respectively, based on either one of the pitch information, the fingering information and the time information stored in the storing unit;
- and
- a whole difficulty level calculating step of calculating a whole difficulty level of music based on the separate difficulty levels calculated at the separate difficulty level calculating step.
