In music, timbre ( /ˈtæmbər/ TAM-bər (American English), /ˈtæɪmbər/ TAIM-bər (British English), or /ˈtɪmbər/) also known as tone color or tone quality from psychoacoustics, is the quality of a musical note or sound or tone that distinguishes different types of sound production, such as voices and musical instruments, string instruments, wind instruments, and percussion instruments. The physical characteristics of sound that determine the perception of timbre include spectrum and envelope.
