===Sound quality===
Quality of a note refers to differences in the sound produced by different sources. A tone from a single frequency is a pure tone. However, a violin’s string vibrates in more than one way at the same time. The tone from the entire length moving back and forth is the fundamental tone. The tones from part of the length moving one way while another part is moving another way are called overtones, also called harmonics. They happen at the same time as the fundamental, and add to and subtract from the fundamental’s wave. The note played is the fundamental. Its quality is affected by the length’s harmonics. Two good singers have a different sound quality, partly because their different vocal chords produce different overtones.<ref name="Harris & Hemmerling, Chapter 19" />
