Piano Game (Music Room)

Hint 1 of 6:

For those of you who aren't familiar with a piano keyboard, the white keys
labelled with letters A through G.  After G comes another A and so on.  Black
keys are labelled with the letter of the white key to the left and the "#"
symbol.  So the black key to the right of C is C#.

Hint 2 of 6:

The first note that's played is a B.

Hint 3 of 6:

Then comes the B in the next octave (7 white keys to the right), F#, and G.
