The "Harp" and "Psaltery" of King David

No historical personage comes more readily to mind than the biblical King David when the word "harp" is mentioned. Yet the instrument translated "harp" in the King James Version (kinnor) was not a harp at all, but a lyre. The other stringed instrument David played, translated "psaltery" by the KJV (nevel), was likewise not a psaltery -- and it may not have been a true harp either (if by "harp" we mean a more-or-less triangular instrument with the strings perpendicular to the soundbox, according to the musicological definition).
