Harp: (Heb. kinnor), the national instrument of the Hebrews. It was invented by Jubal (Genesis 4:21). Some think the word kinnor denotes the whole class of stringed instruments. It was used as an accompaniment to songs of cheerfulness as well as of praise to God (Genesis 31:27; 1 Samuel 16:23; 2 Chronicles 20:28; Psalm 33:2; 137:2).

In Solomon's time harps were made of almug-trees (1 Kings 10:11,12). In 1 Chronicles 15:21 mention is made of "harps on the Sheminith;" Revised Version, "harps set to the Sheminith;" better perhaps "harps of eight strings." The soothing effect of the music of the harp is referred to 1 Samuel 16:16,23; 18:10; 19:9. The church in heaven is represented as celebrating the triumphs of the Redeemer "harping with their harps" (Revelation 14:2).
