Andrew, how delightful to have an opportunity to reinvent yourself as a player... like falling in love with a whole new instrument, I would imagine.There have been some great discussions along the lines you are suggesting. I wish I could recall the thread titles easily, and lay them all here for you to see... maybe someone else will be able to find some of them. And I will look tomorrow.
But I think one question has to be-- and only you can answer it-- what new music do you want to play-- what's exciting to you as a musician right now? And what sort of palying style would best support that? Well, it's more than one question... but maybe a line of thought worth taking before plunging into technique?
