Patent ID: 7435169

Claim:
A music playing apparatus having a controller allowing a user to provide input to the music playing apparatus and a storage location storing at least sound data, comprising: first sound output programmed logic circuitry for outputting music from the sound data stored in said storage location in response to input from said controller; a history storing location for storing a history of the input from said controller in said storage location; playing tempo detecting programmed logic circuitry for detecting a tempo played by the user based on the history of the inputs over a predetermined time period; determining programmed logic circuitry for determining whether or not the tempo detected by said playing tempo detecting programmed logic circuitry and a current input have a predetermined relationship; and second sound output programmed logic circuitry for outputting a sound effect from the sound data stored in said storage location in dependence on the predetermined relationship, the sound effect being different from the music and the sound effect being indicative of user performance.
