Giovanni Doni is known for having changed the name of note "Ut" (C), renaming it "Do" (in the "Do Re Mi ..." sequence known as solfège). He convinced his contemporaries to make the change by arguing that 1) "Do" is easier to pronounce than "Ut," and 2) "Do" is an abbreviation for "Dominus," the Latin word for The Lord, who is the tonic and root of the world. There is much academic speculation that Giovanni Doni also wanted to imprint himself into musical canon in perpetuity because "Do" is also ulteriorly an abbreviation for his family name.
