摘要： In a fingering information analyzer, tone pitch information indicative of each tone pitch of a series of musical notes supplied from a flexible disc or a performance information memory is analyzed to produce fingering information indicative of a performance finger for each of the musical notes. The fingering information is mixed with the tone pitch information and memorized in a fingering memory. When the fingering information is reproduced, a performance finger for each of the musical notes is determined in accordance with a changing direction or variation width of the tone pitch information continual in time series and a changing condition of white and black keys based on the tone pitch information. The tone pitch information and fingering information memorized in the fingering memory is read out in accordance with progression of a musical tune and adapted for performance of the keys on a keyboard and for indication of the performance finger.

摘要： A selected span of a music composition data file containing note data in the MIDI format which discriminates twelve notes per octave is examined with respect to respective tonalities to find an optimum tonality. Out of all the notes contained in the selected span, the number of notes that fall on the intrinsic notes of a tonality is counted with respect to each of the tonalities. The tonality which has the greatest count of intrinsic notes is determined to the optimum tonality. When the music composition is transposed, the chord names are altered according to the amount of the transposition. Then, the altered chord names are subjected to adjustment in expression according to the musical grammar. Accidental signs are adequately determined from among enharmonic notations.
