Psalms 150:5

Praise him upon the loud cymbals - literally, “the cymbals of sound” or hearing. That is, Let there be audibly expressed joy. The allusion here is to an instrument of music that was most distinctly heard in union with other instruments. The sound of the cymbal would be most clearly audible in its accompaniment of the other instruments referred to, as the sound of cymbals, or as the “triangle” would be now. The Hebrew word rendered cymbal means a tinkling, clanging, ringing, as of metal, or of arms; then, a whirring, as of wings (compare the notes at Isaiah 18:1); then, any tinkling or clanging instrument, as a fish-spear or harpoon; then, cymbals, instruments of music. The cymbal, as now used, is an instrument of brass, in a circular form, like a dish, producing, when two are struck gether, a sharp, ringing sound - Webster. An instrument of this kind is evidently referred to here. The word occurs in the Bible in the following places only: Deuteronomy 28:42, rendered locust; 2 Samuel 6:5, rendered, as here, cymbal; Job 41:7, rendered fish-spears; and Isaiah 18:1, rendered shadowing with.

Praise him upon the high-sounding cymbals - The cymbals of joyful voice. On the word teruah, rendered high, see the notes at Psalms 89:16. A loud, lofty sound or shout, as on the reception of a conqueror, is the idea here; and the sense is, that the praise of God was to be celebrated with that which would in the highest sense express joy and triumph.
