Criteria for identifying the person’s voice type:
Short singing voice test for voice classification:
Note: The person who identifies the another person’s voice type must have an absolute/perfect pitch. The person who has an absolute/perfect pitch to sing, especially in a choir, is very advantageous. For choral performances, expect that all choristers should have their own absolute/perfect pitch to stay in tune when singing homophonically, or especially, polyphonically, by striving to be accustomed to the widely accepted tuning system and reference pitch, which is 12-tone equal temperament (12-TET) at 440Hz. Of course, choristers must know how to read and write sheet music.
