The Benedictine monk and choirmaster Guido d'Arezzo (990-1050) noticed that in the Latin hymn Ut Queant Laxis, which was sung in chant for the Feast of St John the Baptist, the tones rise progressively......
Ut Queant Laxis
Resonare
fibris
Mira gestorum
Famuli tuorum
Solve polluti
Labii reatum
Sante Iohannes
In the Western music system, the notes in italics, Ut, Re, Mi, Fa, So, La etc formed the basis of teaching music to children. Do replaced Ut in common usage, probably because the T in Ut could not be sung.
Doe, A Deer
(Text from the soundtrack of movie Sound of Music)
Doe, a deer, a female deer,
Ray, a drop of golden sun,
Me, a name I call myself,
Far, a long long way to go,
Sew, a needle pulling thread,
La, a note to follow sew,
Tea, a drink with jam and bread,
That will bring us back to Do-o-o-o
(Repeat whole verse)
Do-re-me-fa-so-la-ti, Do-so-do
So da la fa me do ray,
So do la te do ray do
When-you-know the notes to sing...
You can sing most any...thing
(Repeat 1st verse)
Do me me, me so so, Re fa
fa, La
ti ti (2)
When you know the notes to sing,
You can sing most anything..... (Repeat 1st verse)
That will bring us back to Doe........
