Introduction:
Musical instruments produce complex sounds that are perceived by the human ear. By analogy with these instruments, the student configures the Spectrason and listens with a speaker to the complex output sound produced. In 3 steps, they will understand how to characterize a musical sound by its pitch and timbre.
