This is the definitive book for developing piano technique, bar none. The other reviews here will testify to this.

I just have one warning...be careful about over doing it. I hurt my hand practicing the Hanon excercises too much. Resist the temptation and don't push yourself too hard. Otherwise you may end up with a repetitive stress injury like I did.

Helps warms up my fingers to enable me to then quickly pick up new pieces; the warm ups are very well varied, fun to play, nice to listen to even.
Sometimes I just play from this book than play actual music as I just like the feeling of flexing my fingers on the piano...

This is my 2nd. The first one got lost and this is my 2nd one. Trust me, this book is a MUST to all keyboardist, pianoist. I use this book at least one hour a day for many years.

The book was what we ordered and it got here fast, even with Amazon Prime shipping.

As a pianist of twenty years and a piano teacher of ten, I highly recommend this book to any serious piano student. While the exercises may seem daunting at first glance, one soon realizes that the repetitive patterns are quite easy to play, even for fairly new pianists who are still learning notes.

As stated in the book, these technical exercises help develop "agility, independence, strength and perfect evenness in the fingers." When practiced correctly and diligently, these exercises will do just that.

As a teacher I have seen great improvement in my students' technique through using this book. I, myself, enjoy playing these exercises for warming up and improving my technique.

Obviously this is not the only good technique book out there, but is a great one to begin with. Also, I would recommend for younger students to try Jr. Hanon - it has the same basic exercises in a much easier to read format.
