In music, the term tessitura (Italian for texture) generally escribes the most musically acceptable and comfortable timbre for a given voice or, less frequently, musical instrument; the range in which a given type of voice presents its best-sounding texture or timbre. This broad definition is often interpreted to refer specifically to the pitch range that most frequently occurs within a given piece, or part, of music. For example, throughout the entirety of Wagner's Ring, the music written for the role of Siegfried ranges from C#3 to C5, but the tessitura is described as high because the tenor phrases are most often in the range of C4 to A4.
