If you’re ever on the lookout for a good piano magazine, Clavier Companion is now offering digital downloads to view on your iPad. I’ve just downloaded the free app and can access the current issue and last 5 back issues for free! In case this is a short-time offer (or error in the system!), get on your iPad and download some issues today!
I can also highly recommend Pianist Magazine as another worth having as a digital or print subscription. Every issue features a CD of pieces and at least 20 pages of sheet music, many with detailed descriptions by famous teachers of how to play and/or teach them. There are also great accompanying videos online by Graham Fitch and others.
