I auditioned for and played in Long Beach City College's orchestra when I was somewhere in Book 4.  No asked, or cared what books my teacher used, although I believe the subject of who was my teacher came up.  I just did one semester because at the time I was getting up for work very early, the rehearsals made for a long day, and especially, the parking situation was dreadful --  A struggle to find parking off campus because there wasn't enough on campus, a long hike back to the car after rehearsal, then a long drive home late at night.

Instrumental playing is based on multiple sensations.  One may hint at them, and induce them on occasion, but ultimately each individual must arrive at these sensations on his own.
