Dunstable - Veni Sancte Spiritus: lines in motion & radiant harmonies

Transcribing Dunstable Veni Sancte Spiritus... This is how you make a composition; you slow the chant down so its expressive shapes can't be perceived except at the structural level. This controls or guarantees the harmony. There is a clarity from moment to moment, and also still a sense of progression reflecting the original form of the free-flowing chant.

These phrase long shifts in the harmony illuminate the words, quite literally: Lumen cordium.

Clear I/V shifts with third based harmonies.

But also strange step wise cadences. Resulting from chant in bass?

Unexpected leaps (Caritas).

Beautiful use of duos, trios and quartets.

Exceedingly sensual successions of major/minor over long A at O lux beatis.

Sustained tone with flowing harmonies around it.

Long successions of sonic harmonies. Radiant.

The lines are somehow fluid and always in motion, yet clear and focused. Each line appears to have its own signature and function, and yet each one works in a collective to produce a unified sound. Is this the definition of harmony?
