Tessitura

In music, tessitura (English: TESS-ih-TOOR-ə, UK also -⁠TURE-, Italian: [tessiˈtuːra]; pl. tessiture; lit. 'weaving' or 'texture') is the most acceptable and comfortable vocal range for a given singer (or, less frequently, musical instrument). It is the range in which a given type of voice presents its best-sounding (or characteristic) timbre. This broad definition is often interpreted to refer specifically to the pitch range that most frequently occurs within a given part of a musical piece. Hence, in musical notation, tessitura is the ambitus, or a narrower part of it, in which that particular vocal (or less often instrumental) part lies—whether high or low, etc.
