Hello

I found your name in an exercise of computer science. I also found a code who look like a bit like your's

	int speakerPin = 9;
	int length = 46;
	String notes[] {"A#4/Bb4","A#4/Bb4","A#4/Bb4","A#4/Bb4","A#4/Bb4","A#4/Bb4","A#4/Bb4","A#4/Bb4","A4","B4","C#5/Db5","C5","D#4/Eb4","D#4/Eb4","D#4/Eb4","D#4/Eb4","D#4/Eb4","D#4/Eb4","D#5/Eb5","D#5/Eb5","D5","D5","D5","E5","E5","F#4/Gb4","F#4/Gb4","F#5/Gb5","F5","G4","G4","G4","G4","G4","G4","G4","G4","G4","G4","G4","G5","G5","rest","rest","rest","rest"};
