for killer technique in both hands in every key
and to develop your reading at the same time (not necessary but its there if you want it)
check out little pishna and pisna 60
dont be scared because it is a classical technique manual this will give you three times the technique that hanon will give you and it is written out in every key so you can use your mind to do the transpositions or look at the music the first exercise is written in the key of c so you could read that and mentally transpose the rest
yo dont get it twisted this book is killer and if you take the itme you will be doing amazing things on you board
I see a lot of you guys out there looking for new chords but you will be surprised how the chords you already know will sound when you combine them with killer technique
ever heard of nate mcnair thats the type of technique I am talking about
Be blessed
check out pishna
Shirmer puts it out it can be ordered from any bookstore

The little Pishna forty eight practice pieces for the piano
and Puishna 60 exersises for the piano
dont even think about pishna 60 until you have played the little pishna
pishna 60 is written in 32nd notes
but you could slow it down but why do that just do the little one first
and in no time you will be playing equally well in every key
