Ornamentations are most likely produced in a combination of various levels from 1-6. The vocal cords producing the pitch, and the vocal tract producing the grid. (see ’Various levels of the vocal tract’).
It is often difficult to make a rapid run of notes even and equal, as the ornamentations often become untidy and un-rhythmic, and the melodic line can get blurred, hazy and indistinct. By using ornamentation technique and applying a grid the singer can achieve an even and equal rapid run of notes.
