What book of piano music would you recommend?

In my opinion, 15 months is too young to begin lessons on any instrument. At that age, a child doesn't have the motor skills necessary to play. It's great that you want to expose your daughter to music- maybe you could get her into a "music and movement" type class. Check out Kindermusik and Musikgarten (can't remember the websites- but you can Google them). They're both intended for babies, toddlers, and young children. It exposes them to music, teaches them basic rhythm, etc. I think Kindermusik even has the option for a parent to become certified to teach (it's an online, at-home program). Or check on the website to find a teacher that's close to you.

And I agree with the first poster- Schaum is NOT the best out there. In my opinion, it's one of the worst. Very outdated- not appealing to young children at all. The best piano method I've found for young children is the Faber series. Their My First Piano Adventure is great for 4-5 year olds. The books themselves are very colorful and eye-catching and the music is fun to play.

If you're a beginner pianist, you most likely won't be playing classical music—at first. However, you can begin developing a technique and acquire facility to play simple classical pieces in short order, with the right instruction. I recommend Alfred lesson books. I also very strongly recommend that you consult your newspaper, local web ads, local musicians, or other available resources to find a quality piano teacher in your area, because tere's much more to learning the piano than can be got from a book and a CD. : D Good luck.

Hmm, http://www.zebrakeys.com/ has wonderful free piano lessons, flash animations, charts, games, and an awesome virtual piano that should do the trick. Best of luck!

I took the John W. Schaumm course. I really enjoyed it, and I've taught from it as well. It's not the best out there, but it's simple and it works.
