Why Must Read A Dozen a Day Book 1 (A Dozen a Day Series)?

I'm returning to the piano after a 20-year hiatus (grew up with a piano in the house, studied for a dozen years, even had a few students in high school), and suffice it to say, I'm rusty! I never knew about the Dozen a Day series when I was younger, but I wanted to pick up a few books to brush up on sight reading and build muscle in my fingers again. I type a lot, but found that sitting down to play, my typing fingers couldn't hack it on the piano keys. I researched the best books for warm-ups, and this series popped up on a few sites. I love it! The warm-ups are a nice mix of tempos and rhythms, and I appreciate the staccato and legato exercises to strengthen my muscles... and to play with the emotional element of how I play the notes. The songs are quick, and sound nice enough that the neighbors can enjoy when they overhear. It's definitely helping build muscle strength and sight reading back up, as well as muscle memory and tone recognition. I'd definitely recommend it to anyone like me who is returning to the piano and wants something relatively quick and easy to practice... that works!
