Abstract:
A music performance apparatus comprising:a plurality of performance operators corresponding to a plurality of tone pitches; a performance guide device adapted to provide a performance guide display for indicating which of said performance operators is to be operated; a performance data supplying device adapted to supply performance data of an optionally selected music piece, said performance data containing at least tone pitch information, a transposition setting device adapted to set a transposition value for the performance data, wherein a user of the music performance apparatus utilizes the transposition setting device to set the transposition value; a processor coupled with at least said performance guide device, said performance data supplying device and said transposition setting device, said processor being adapted to transpose the performance data by controlling the tone pitch information in accordance with the transposition value set by said transposition setting device and cause said performance guide device to provide the performance guide display based on the controlled tone pitch information, wherein the performance guide device is adapted to provide the performance guide display for the music performance apparatus for indicating which of said performance operators is to be operated, and wherein a transpose of the performance data is the same as the performance data or a variation of the performance data, wherein the variation differs from the performance data in terms of a musical key in which the performance data is stored; a tone generator device adapted to generate a tone at least in response to operation of any of said performance operators, wherein the transposition value set by said transposition setting device is not applied to a tone that is to be generated via said tone generator device in response to the operation of said performance operator; and a general transposition setting device adapted to set a general transposition value wherein a pitch of the tone to be generated via said tone generator device in response to the operation of said performance operator is controlled in accordance with the general transposition value set by said general transposition setting device.
