What does 'diapason' mean in this sentence?

That we on Earth with undiscording voice / May rightly answer that melodious noise; / As once we did, till disproportion'd sin / Jarr'd against natures chime, and with harsh din / Broke the fair musick that all creatures made / To their great Lord, whose love their motion sway'd / In perfect Diapason, whilst they stood / In first obedience, and their state of good.
