And He Shall Purify
The chorus's running semiquavers race along the roofline as fine bright lines, burning off the dark impurities in sparks, until the whole house shines clean gold.

About this scene
The chorus's running semiquavers as bright lines tracing the roofline, burning off the dross.
The house starts dull and dirty: a murky ember glow, scattered with darker red blotches, the impurities. Every sung line is a fine white-gold tracer on the roofline: each note carries its head on along the house, a little farther up or back with every interval the voice sings, turning back at the ends, so the long semiquaver runs of "purify" are quick bright lines racing and zig-zagging along the roofline, a fading trail behind each. Wherever a tracer's head passes over an impurity, it burns off in a spark of gold, and the house beneath it is cleaner.
The sopranos give the subject alone, over the basses; then the basses take it up, the altos, the tenors, and at last the whole chorus is running at once, the strings with them, the lines crossing, sparks flying all along the house, the glow beneath turning from murk to gold as the dross burns away.
Then the close: "that they may offer unto the Lord an offering in righteousness", the chorus together, fortissimo. On its first chord the last impurities flash off together, and the house is clean gold from end to end, Side included, surging with every chord while the violins' semiquavers still trace across it. On "righteousness" it settles into one steady, clean gold, and holds through the strings' last bars.
The music is Handel's own: Messiah No. 7, the opening to the full chorus's "and He shall purify" (bars 1-16) and the close from "of Levi" to the end (51-58), transcribed from Prout's full score (Novello, 1902) into and_he_shall_purify.musicxml and timed by scripts/score_excerpt.py at Prout's Allegro. Handel's strings and the chorus; the chorus sung on strings with oboes and a bassoon doubling, the organ under the close.
