SCORING
HOW IT JUDGES
Each pitch on a BBb 4-valve tuba has multiple legal fingerings (the 7th-partial Ab gets ignored, for everyone's sanity). Any common alternate counts as correct. The trainer plays the note when you nail it so your ear can lock onto the pitch.
In SONG mode the melody walks forward when you play the right combo. Miss three times in a row and the hint kicks in automatically.
