Boyd’s Bible Dictionary:

Flute
Type of perforated wind instruments, as the harp was of stringed instruments (1 Sam. 10:5; 1 Kings 1:40; Isa. 5:12).

Concise Bible Dictionary:

The simplest of musical instruments, often made of a reed, with holes to vary the notes. They were sometimes double, as seen on the Egyptian monuments, and in present use in Egypt: a number of them fastened together was called an “organ” (1 Sam. 10:5; 1 Kings 1:40; Isa. 5:12; Isa. 30:29; Jer. 48:36; Ezek. 28:13; 1 Cor. 14:7).
