Off the top of my head, I'd say that almost all woodwind and the better vocal vibrato are AM rather than PM. Good brass vibrato can be either, but on the classical side it's more AM. All these vibratos are produced by the diaphragm, not the throat. All string vibrato, of course, is PM. So a vocal wobble can be the result of either excessive and slow AM from the diaphragm or excessive and slow PM in the throat. Virtually all voice teachers preach that a vibrato is an inevitable result of good vocal production. Translated, that means the it's an inevitable result of the kind of vocal production they teach, which is operatically inclined. An increasing number of early music singers are finding that the lighter, unforced technique appropriate to early music allows much more flexibility and much more controlable vibrato, including real trills rather than forced vibrato trills. Good jazz singers never thought otherwise!
