Musical notes using syllables: Do, Re, Mi, Fa, Sol, La and Ti. The names of musical notes can also be represented using syllables, as Do, Re, Mi, Fa, Sol, La and Ti. Some languages use Si instead of Ti. These musical note names match the C major scale, the one we sang before. That means that: Do is C; Re is D; Mi is E; Fa is F; Sol is G; La is Plus, if you learn the Latin system, you'll come across the tonic (do), supertonic (re), median (mi), subdominant (fa), dominant (so), submediant (la), and leading tone (ti). Oh, and Do-Re-Mi isn't always a fixed structure. There's the 'Fixed do' system, which says that no matter what key the music is in, 'do' will always be a WMRqCbn.
