mi
Third solfège tone
Mi is the third note of the musical scale in solfège, the system where syllables represent pitches: do, re, mi, fa, sol, la, ti.
It gained widespread recognition from the song "Do-Re-Mi" in *The Sound of Music*: Mi, a name I call myself.
In fixed-do systems, mi always refers to the note E. (Capitalized MI is the postal abbreviation for Michigan.)
