Harp: (Heb. kinnor), the national instrument of the Hebrews. It was
invented by Jubal (Gen. 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 (Gen. 31:27; 1 Sam. 16:23; 2 Chr. 20:28; Ps. 33:2;
137:2).
In Solomon's time harps were made of almug-trees (1 Kings
10:11, 12). In 1 Chr. 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 Sam. 16:16, 23; 18:10;
19:9. The church in heaven is represented as celebrating the
triumphs of the Redeemer "harping with their harps" (Rev. 14:2).
