 Giovanni Battista Doni is known for having changed the name of note "Ut" (C), renaming it "Do" (in the "Do Re Mi ..." sequence known as solfège).A seventh note, "Si" (from the initials for "Sancte Iohannes," Latin for St. John the Baptist) was added shortly after to complete the diatonic scale.In anglophone countries, "Si" was changed to "Ti" by Sarah Glover in the nineteenth century so that every syllable might begin with a different letter (this also freed up Si for later use as Sol-sharp).
