Ut queant laxis—(Play together a Gregorian Chant)

0:00 Ut queant laxis on bass recorder 0:55 Ut queant laxis with drones 2:12 Play together version Ut queant laxis is a Gregorian chant which is useful for teaching singing because of the way it uses successive notes of the scale: the first six musical phrases of each stanza begin on a successively higher notes of the hexachord, giving ut–re–mi–fa–so–la; though ut is replaced by do in modern solfège. The naming of the notes of the hexachord by the first syllable of each hemistich (half line of verse) of the first verse is usually attributed to Guido of Arezzo. Guido, who was active in the eleventh century, is regarded as the father of modern musical notation. He made use of clefs (C & F clefs) and invented the ut-re-mi-fa-sol-la notation. The hymn does not help with the seventh tone as the last line, Sancte Iohannes, breaks the ascending pattern. The syllable si, for the seventh tone, was added in the 18th century.
