Shoshannim

Lilies, the name of some musical instrument, probably like a lily in shape (Ps. 45; 69, title). Some think that an instrument of six strings is meant.

(lilies). "To the chief musician upon Shoshannim" is a musical direction to the leader of the temple choir which occurs in (Psalms 45:1; 69:1) and most probably indicates the melody "after" or "in the manner of" (Authorized Version upon") which the psalms were to be sung. Shoshannim-eduth occurs in the same way in the title of (Psalms 80:1) ... As the words now stand they signify "lilies, a testimony," and the two are separated by a large distinctive accent. In themselves they have no meaning in the present text, and must therefore be regarded as probably a fragment of the beginning of an older psalm with which the choir were familiar.
