New to this list, so I hope this is the right place to post my question. I've looked at the music teachers listed here on BPN and there are 3 we are considering: Ernie Mansfield, Alexi Erenkov, and Jon Swann. This is for a high school senior who already plays classical violin and a bit of guitar/electric guitar. Now she's taking up the sax & is in her high school's symphonic band, but as a total beginner on this instrument could use some outside instruction/coaching. Have you had either a good or bad experience with any of these teachers? Or maybe you have another suggestion? Thanks for any advice you can give us.
