Happy November! For today only (11-2-15), get the free Kindle edition of The Practice of Practice (a longer-form read on music practice) and Practice Like This (all killer, no filler version on practice in general).
Warning: Don’t fall for Amazon’s unfortunate button placement. You DO NOT have to sign up for Kindle Unlimited to get the books for free. You must “purchase” the books by putting them in your cart, and then check out. You’ll be “charged” $0.00, and then you’ve got the books!
