In order to study differences in the piano performance between skilled and unskilled players, we quantitatively compared performing tendencies using MIDI data obtained from the performances of an easy piece. It was found that there were some differences between both groups of players on the following points : expression of the phrase with dynamics, loudness of the accompaniment to the melody, existence of the ritardando at the end of the piece, overlapping time among successive notes in the legato phrase, and so on. Additionally, a listening experiment was carried out to investigate the influences of these aforesaid differences on audience evaluation. The results showed a possibility that these differences adversely affect the audience evaluation.
