Timbre

In music, timbre (French, IPA /'tæmb?r/ as in the first two syllables of tambourine) is the quality of a musical note or sound which distinguishes different types of sound production or musical instruments. The physical characteristics of sound which are used in the determination of timbre are spectrum and envelope with psychoacoustics or human perception also determining the perceived quality of a sound. Timbre is what, with a little practice, people use to pick out the saxophone from the trumpet in a jazz group or the flute from the violin in an orchestra, even if they are playing notes at the same pitch and amplitude (or notes which are otherwise equal). Timbre has been called the psychoacoustician's waste-basket as it can include so many factors.

American Standards Association definition

The American Standards Association defines timbre as " that attribute of sensation in terms of which a listener can judge that two sounds having the same loudness and pitch are dissimilar". A note to the 1960 definition (p.45) adds that "timbre depends primarily upon the spectrum of the stimulus, but it also depends upon the waveform, the sound pressure, the frequency location of the spectrum, and the temporal characteristics of the stimulus."
