Claims

[Claims for Utility Model Registration] (1) Automatic performance data output means for sequentially outputting automatic performance data constituting a musical piece; chord designation means for designating a chord by operating an operator; and from the automatic performance data output means. converting the pitch indicated by the outputted automatic performance data into a pitch corresponding to the chord specified by the chord specifying means, based on the chord progression of the musical piece and the chord specified by the chord specifying means; An automatic performance device comprising: a converting means; and a musical tone generating means for generating a musical tone having a pitch converted by the converting means. (2) The automatic performance data output means outputs the automatic performance data of the melody part and the automatic performance data of the accompaniment part constituting the musical piece, and the conversion means converts the pitch indicated by the automatic performance data of the accompaniment part, 2. The automatic performance apparatus according to claim 1, wherein the pitch is converted to a pitch corresponding to a chord specified by the chord specifying means. (3) the converting means is a first converting means that converts the pitch indicated by the automatic performance data into a pitch corresponding to the predetermined chord based on the chord progression of the song and the predetermined chord; The pitch corresponding to the predetermined chord converted by the first converting means is determined based on the difference between the predetermined chord and the chord specified by the chord specifying means, and the chord specified by the chord specifying means. 3. The automatic performance apparatus according to claim 1, further comprising a second converting means for converting the pitch into a pitch corresponding to the pitch.
