I love working out and building up the muscles in my body. As a musician we need to build up the muscles in our fingers and create muscle memory so we can play smoothly the passages in our music.
I find that Hanon is the best for this. If you start out slow and then build up speed moving from one exercise to the other you will fly through the entire book in no time.
Try this first exercise of Hanon. If you like it you should learn the entire book. You will be glad you did. Hanon Exercise #1
If you want to play like “butter” on the guitar I recommend Hanon for Guitar. This is a great book with the tabs to make it easier for you if you can’t read the music. You will get your fingers whipped into shape by playing these daily.
