Shoshannim
From Wikipedia, the free encyclopedia
Shoshannim (Hebrew ששנים, 'lilies') is mentioned in Psalm 45 and Psalm 69. Its meaning in these Psalms in uncertain. Some believe it to be a kind of lily-shaped straight trumpet [1], a six-stringed instrument [2], a word commencing a song [3] or the melody to which these psalms were to be sung [4].
