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? (- Thanks, Carmine

Get one of the tuners that can play back each pitch and take it apart. Have a central speaker on the poster, and on the poster board put conductive fabric over the buttons, and behind the fabric are two disconnected wires. When the fabric is pushed against the end of each wire, a circuit is completed and the pitch plays. Just an idea though, i really wouldn't know how to make a separate button for each pitch. Good luck. I play Tuba, Yay!

If you have anyone available with basic woodworking skills, you can also create a set of paddle keys that pivot on a rod. They are placed over the real keys of a cheap/toy electronic keyboard held in a frame to "extend" the real keyboard. You could also paint the paddles with the note names or different colors. They also have these baby crib kick toys that are similar to what you need. Maybe some parents have them that they can donate. Good luck.

You could dismantle a cheap electronic keyboard, place a switch under each button?
