A Dictionary of Music and Musicians/Coloratur
Appearance
COLORATUR. Vocal music coloured, that is, ornamented, by runs and rapid passages or divisions, where each syllable of the words has two or more notes to it. It is what the old school called 'figurato'—figured. Coloratur may be employed in slow or fast airs, plaintive or passionate. Almost all the great airs contain examples of it. The following example from the Messiah:—
contains both plain and coloratur passages. On the other hand, 'How beautiful are the feet' (Messiah), or 'Hear ye, Israel' (Elijah), are not coloratur songs. Nor are passages in which each note has its syllable, as in Schumann's 'Die Rose, die Lilie,' or Mozart's 'La piccina' (Madamina), however rapid they may be.[ G. ]
