I have been doing SQUIRTS Drills I found in an old Leon Merian book, since the writing is faded I can't tell why these should be done. However I would assume it is for strenghening your buccinators and range.

My ? is - has anybody here done these types of drills, and should they be done in a very slow manner at first or just pop the the note up?

Thanks Guys
