"title": "Tremendous Tool to Learn Left Hand",
"body": "I have a music degree and have been playing other instruments professionally for over 25 years. I recently wanted to learn accordion but found the left-hand stradella bass to be intimidating. This app not only has the left hand to practice but I can adjust the buttons size, angle, and spacing to match my own accordion. Now I can practice the hardest part of accordion playing anywhere on my phone. Thank you, Accordion Free!",
