Dear ALL. i am working on the simple keyboard on page http://arduino.cc/en/Tutorial/Tone3.
The code says

sketch_jun06a:27: error: 'NOTE_A4' was not declared in this scope
sketch_jun06a:27: error: 'NOTE_B4' was not declared in this scope
sketch_jun06a:27: error: 'NOTE_C3' was not declared in this scope

I am a total beginner. Does anyone know how to solve this. I just copied the tutorial...

Thanks Dinie

To make this file, click on the "new Tab" button in the upper right hand corner of the window. It looks like this:
