Travel Inside the Mouth - Point 5

At 1:50 he plays a 2", which is a bend that uses the back of the tongue to necessitate the large chamber needed to tune the mouth to a low pitch. At 1:51 he plays a 3", which is a bend that uses the middle-back of the tongue, further forward in the mouth, due to the fact that it's a higher pitched bend than the 2". At 1:53 he plays 3 draw and moves his tongue down slightly to tune the pitch of his mouth to the 3 draw and then plays 3+ and he really opens up to give that note a big, resonant sound (large chamber = big tone). The 3 draw after his bend holds the secret to vibrato... we'll talk about that a little bit later.
