An automatic musical interval guitar is provided to improve portability as a long and complicated base plate is not necessary and to use in a karaoke system. An automatic musical interval guitar comprises a memory unit, a modulated signal input unit(13), a harping signal input unit(12), a controller(19), and a sound output unit(16). In the memory unit, tune data in which musical intervals are recorded as the performance time is stored. The modulated signal input unit inputs the signals regulating the height of the musical interval in musical performance. The harping signal input unit inputs the signals to output the adjusted musical interval. The controller analyzes signals inputted from the modulated signal input unit and the harping signal input unit and the tune data and generates or modulates proper sound and outputs the result signals to the sound output unit. The sound output unit outputs the sound signals by receiving the result signals. |
