The text "Sing ye choirs of angels / Sing to God on high" is a hymn text that must be matched to the correct tonic sol-fa notation. The key is to align each syllable of text with its corresponding sol-fa note and rhythm.
Counting the syllables: "Sing ye choirs of an-gels" gives six syllables, and "Sing to God on high" gives five syllables, for a total of eleven syllable-sounds across the two lines.
The correct representation is m:m|m:f|s:-|m:-|f:f|r:t|d:-|-:-||. In this notation, each syllable maps to one sol-fa note in a simple, hymn-like rhythm:
"Sing" = m, "ye" = m
"choirs" = m, "of" = f
"an-" = s (held: s:-)
"-gels" = m (held: m:-)
"Sing" = f, "to" = f
"God" = r, "on" = t (ti)
"high" = d (held: d:-, -:-)
The melody moves stepwise and by small intervals, characteristic of a straightforward hymn tune. The held notes at the ends of phrases (indicated by ":-") give the natural breathing points in the text. The other options contain dotted rhythms, extra notes, or rhythmic subdivisions that do not match this simple hymn setting.
