G2789–κιθαρίζω–kitharizō

Even inanimate things--flutes or harps, for instance--when yielding a sound, if they make no distinction in the notes, how shall the tune which is played on the flute or the harp be known?

κιθαριζόμενον; kitharizomenon “is being harped?”

And I heard music from Heaven which resembled the sound of many waters and the roar of loud thunder; and the music which I heard was like that of harpists playing upon their harps.

κιθαριζόντων kitharizontōn “harping”
