He was despised, the often ten minute plus scena from Handel’s Messiah, is a particularly challenging aria for countertenors to deliver well. The tessitura (it was originally written for Ms. Cibber, a singer reported to have had a very broadway-esque limited range) sits low, and the text asks for a dramatic declamation and cutting tone. Listen to the way that American countertenor Bejun Mehta is able to sing on an efficiently produced partial length of vocal fold (his head voice) all the way down to A3 (the aria is in the dark key of Eb, but here is performed down a half-step at A4=415). This is a great illustration of my description of a countertenor’s lower alto range from my previous post on countertenor technique.
