McCarthy Music is a great app that allows me can turn my mobile device into a full piano with useful features. Also, this application can also act as a music teacher and guide me through the basic lessons first, until I can create the smooth melodies by myself. It is wonderful, it makes me very surprised about what it brings. With 8 different songs I can start learning from the best basics. Learn to play the piano has always been my dream and this app will be a solution can not be more ideal. It also gives me moments of entertainment and great fun. I really like this app.
