That at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, dulcimer, and all kinds of musick, ye fall down and worship the golden image that Nebuchadnezzar the king hath set up:
At what time ye hear the sound of the cornet - a wind instrument, like the French horn, is meant.
Flute - a pipe or pipes, not blown transversely, as our "flute," but by mouth-pieces at the end.
Sackbut - a triangular stringed instrument, having short strings, the sound being on a high sharp key.
Psaltery - a kind of harp.
Dulcimer - a bagpipe, consisting of two pipes thrust through a leather bag, emitting a sweet plaintive sound. [Chaldaic Sumponya, the modern Italian Zampogna, Asiatic Zambonja, Hebrew cuwmponªyaah (H5481), Greek sumfoonia (G4858).]
Fall down - that the recusants might be the more readily detected.
