txtDefinition=The spectrum of the higher-{\uldb pitched}{\v 92779} frequencies that accompany the fundamental (the basic frequency that determines our perception of pitch) of a {\uldb tone}{\v 100650} and determine its {\uldb timbre}{\v 99845}. Overtones are also called harmonics or partials. For our purposes, we need to know only that the first overtone is the {\uldb octave}{\v 90046}, which is the distance between the {\uldb cello}{\v 76489} and {\uldb viola}{\v 105422}, and that the second overtone is the {\uldb perfect fifth}{\v 91593}, which is the {\uldb interval}{\v 84848} between the viola and {\uldb violin}{\v 105626}.
