How to make a simple cheep music note generator
I teach music in Elementary school(s) and have a class with several special needs students. I'd like to make a music note generator like a simple keyboard but I want to use buttons they already have.
Example. While the rest of the class is playing recorder. These students have a large piece of black poster board with several round dots with note names. While the group plays these students push on the round dots.
I would really like to be able to make those dots play the same pitch as the recorders. Just one simple sound with about 6 or 7 different notes. i.e. from D to low D or C.
Did I mention that this should be cheep too? (-
