Violins as complex sound signal
Oscilloscope graph of violin playing. Example of complex tone as overlapping of simple tones.
With the violin, several simple tones overlap their upper harmonics to form “sounds" and the sounds and tones of several strings form complex “tone and sound mixtures". A complex periodic sound signal is formed through the combination of simple harmonics or partial tones.
