Tessitura – Definition
Tessitura is the range of notes in which a voice or instrument performs most comfortably and naturally. Unlike the total range, tessitura refers to where most of the notes in a piece are concentrated.
What is Tessitura?
Tessitura differs from a voice’s or instrument’s overall range. A melody may have a relatively small range yet still have a high tessitura if most of its notes remain in the upper register. Likewise, a low tessitura places most of the music in the lower part of the available range.
The concept is especially important for singers, but it also applies to musical instruments, each of which has registers that sound more characteristic and comfortable than others.
Why is Tessitura important for pianists?
Pianists often need to adjust the key of a song to suit a singer’s tessitura rather than simply their highest and lowest notes. Choosing the right key allows the vocalist to sing with greater comfort, better tone, and more expressive freedom.
Understanding tessitura also helps pianists write and arrange music that fits the natural strengths of different voices and instruments.
