ABSTRACT:
An apparatus to assist the musical instruction of a student including one or more tone sources (e.g., flute, human voice, violin) playing monophonically as inputs, means to quantify aural parameters of pitch, amplitude, duration, and timbre of inputs, means to visually store and represent temporal history of said, means to store and playback audio signal of inputs, and means to arrive at and display musical related pitches. A waveform analyzer is used to control a tunable low-pass filter in the pitch tracker and preform spectral estimation of timbre. Pre-recorded music instruction and a karaoke player are used as examples of reference tone sources. Visual representation of aural parameters can provided as video output.
