Charles Ellicott Commentary Psalms 150:5

"Praise him with loud cymbals: Praise him with high sounding cymbals." — Psalms 150:5 (ASV)

Cymbals. —Hebrew, tseltselîm (2 Samuel 6:5), a word evidently formed to express the sound of the instrument. Two kinds are evidently indicated in this verse, the “loud” cymbals (literally, cymbals of hearing) , and “high-sounding” (literally, of tumult) . As the Arabs use at present a larger and smaller instrument (see Bible Educator, 2, 211, 311), it is possible that the same distinction is made here, but which would be the larger instrument it is impossible from the Hebrew to determine.
