Genesis 4:21

Such as handle the harp and organ. “Harp,” kinnor. The world’s first musical instrument, the “harp,” is mentioned 42 times in the OT (see Ps. 33:2; etc.). The word kinnor is always translated in the KJV “harp,” though it is actually a lyre. Many ancient pictures of this instrument from Egypt, Palestine, and Mesopotamia bring us a clear idea of what the kinnor was like. These pictures represent the instrument as consisting of a sounding board across which strings are stretched. In the earliest instalments the strings run parallel, but in later models they diverge as they extend outward.

The origin of the word translated in the KJV “organ,” in the RV “pipe,” and identified by some with the bagpipe, is not so certain as that of the lyre. Whatever the correct explanation of the name may be, all modern scholars agree that the instalment was a flute. This instrument is still played by the shepherds throughout the Near East.
