My sketches are encountering the following error statement: 'NOTE_' was not declared in this scope.
I have written the sketch exactly as previously accepted tone sketches and cannot find errors in construction.
What am I doing incorrectly? Is my reference *include "pitches.h"" not enough reference for the melody I write?

did you write
#include "pitches.h"

Hey Rosso!
Did you find out how to change the pin nr?

It's a very useful library!

So where is E sharp? Some notes don't have their sharps and no notes have their flats. Is there a complete library for the pitches somewhere?

This Gist was created 8 years ago (2012) so that it was discoverable by searching Github itself.

It came from the very same code paste that still exists in the official toneKeyboard tutorial.

Oh yes, I know, I've used this "library" (really just a list of note frequencies, I don't think of it as a library) extensively recently and I always thought I maybe just had an older example sketch. I've been trying to add the sharps myself recently and I'm worried I might be getting them wrong. If there's a slightly updated version that would be nice, but I assume I'll have to do this myself, although I really don't trust my accuracy.

As you may see on the piano, some black keys are missing. E sharp is just the same as F. F flat is same as E. Same with B sharp is just C, and C flat is just B. I see the definitions only define sharps, A sharp is the same as b flat. Probably done like this to save memory as it is a limited resource.

You can easily add E sharp as follows:
#define NOTE_E4 330
#define NOTE_ES4 349
#define NOTE_F4 349
