As a matter of interest (or not as you wish)

The term "Quire" used by the West Gallery Association very likely came from the morning service or Mattins in the book of common prayer where, at one point there was a statement "In quires and places where they sing, here follows the anthem". i.e. a chance for the choir to show off <g>

Solmisation referred to earlier is very old indeed. About 1000 years in fact. The system was devised by an Italian Monk, Guido d'Arezzo who was born around 995 CE. He used the first syllable of a hymn to St. John where each line started one note higher as an aid for teaching monks to chant the offices.

Something like this

Ut queant laxis
Resonare fibris
Mira gestorum
Famuli tuorum
Solve polluti
Labi reatum
Sante Johannes

Thus we get Ut Re Mi Fa So La

Si was added later from the initials of "Sante Johannes" (Remember in Mediaeval Latin, I and J were the same letter)

In English we have replaced "Ut" with "Do", but the French and Italians still use "Ut"

That we still use these syllables as an aid to singing is a remarkable testament to Guido's original idea.
