John Calvin Commentary Daniel 3:4-5

"Then the herald cried aloud, To you it is commanded, O peoples, nations, and languages, that at what time ye hear the sound of the cornet, flute, harp, sackbut, psaltery, dulcimer, and all kinds of music, ye fall down and worship the golden image that Nebuchadnezzar the king hath set up;" — Daniel 3:4-5 (ASV)

I do not know what kind of musical instruments these were.
