As a music teacher for special needs students, its a WOW!

I am supposed to provide students with severe cognitive disabilities access to the music curriculum. I think that 50 in 1 is a great idea because it shows both the pitch and duration one needs to play songs from the apps library. I know my students will both get it and enjoy it!!! Thank you.
Id like to request both" Row, Row, Row" your boat and "Are You Sleeping?" with a simple one finger harmony of only the root of I or root of I and root of V. This way a teacher could use it to teach elementary harmony.

I love that you did melody and harmony parts in your app. They are too difficult for my physically and mentally challenged student.
