Vocal instrumentation
The largest quantity of literature in Western music has been written for the chorus. The choir, an instrument capable of great subtleties of colour, has been a favourite of composers for centuries. The range of most individual singing voices is rather limited. Choral singers, who usually have a limited amount of training, are capable of a range of about an octave and a fifth, which is considerably smaller than the range of individual instruments. Singers are usually not capable of singing wide leaps, that is to say, notes that are far apart in range. Great skill is required in the musical setting of the text in a choral work. Attention must be paid to the vocal qualities of vowel sounds as well as to the way in which the consonants are treated.
For centuries composers have been intrigued with the combination of voices and instruments, and many of the most important compositions in Western music have been written for chorus and orchestra. Almost every major composer of the past three centuries has written for choir and large instrumental ensembles.
