Muthlabben
Smith’s Bible Dictionary (1863)
“To the chief musician upon Muth-labben” is the title of (Psalms 9:1) which has given rise to infinite conjecture. It may be either upon the death (muth) of the fool (labben), as an anagram on Nabal or as Gesenius, “to be chanted by boys with virgins’ voices,” i.e. in the soprano.
