Quod uni ex minimis meis fecistis

The differentia of this antiphon clearly shows the overlooking of precise notational standards: the second to fourth pitches 'a-G-F' apparently seem to be part of a single three-sound neume (hence the differentia appearing as only having four neumes for four syllables), but each of those pitches reports a single syllable, resulting in the correct succession of six pitches and the code 75d, of decidedly French circulation.
