Definition & Meaning of "tessitura"

What is "tessitura"?

Tessitura refers to the range within which a singer or instrument performs most comfortably and effectively. It is the part of the vocal or instrumental range where the performer’s voice or sound is most at ease and produces the best tone. Tessitura is not about the absolute highest or lowest notes that can be reached but rather the range where the majority of the music is sung or played. In opera and choral music, understanding the tessitura helps in choosing roles and compositions that suit a performer’s natural strengths.
