Charles Ellicott Commentary Psalms 150:4

"Praise him with timbrel and dance: Praise him with stringed instruments and pipe." — Psalms 150:4 (ASV)

Timbrel and dance.— See Psalms 149:3.

Stringed instruments.— Minnîm. Literally, parts, so threads, so here, as in the Septuagint and Vulgate, “with” or “on strings.” (See Note, Psalms 45:9.)

Organs.— Hebrew, ‘ugab, which has been variously identified with the syrinx, or Pan’s pipes, of the Greeks, with the “bagpipe,” and even with a rude instrument embodying the principle of the modern organ. (See Bible Educator, 2:70, 183, 229.)
