Structure of Choirs and Chorus Singing means Choirs are led by a conductor or choirmaster.  Most often Choirs consist of four sections intended to sing in four part harmony, but there is no limit to the number of possible parts as long as there is a singer available to sing the part. 

Thomas Tallis wrote a 40-part motet entitled Spem in alium, for eight choirs of five parts each; Krzysztof Penderecki's Stabat Mater is for three choirs of 16 voices each, a total of 48 parts. Other than four, the most common number of parts are three, five, six and eight.

Choirs can sing with or without Musical Instrumental Accompaniment. Singing without accompaniment is called Cappella Choir Singing or Unaccompanied Choir Singing.

Choirs are often categorized by the -

i)          Choir Voices they contain;

ii)         Choir Institutions & Communities in which they practice and perform; and

iii)        Type of Music Choirs and Chorus Singers Perform.
