Code Music Notation

note = C
note.play(lefthand, loudly)

scale = [C, C#, F, G, G#]
scale.choose.play

10 do
	scale.choose.play -- here you play a random note from scale
	1.wait; -- wait for a second
end

Code Music Notation

if(lefthand.busy == true) {
    righthand.copy(lefthand.note+7) -- the right hand is angry!
} else {
    4 do
        scale.play(righthand) -- slowly but concentrated
    end
}
