(The meaning is obscure. But its signification where it
occurs elsewhere than in the titles of Psalms is equivalent to the English word "instruction," or to become wise by instruction; hence, Ps 47:7: "Sing ye praises with understanding.")
(Authorities, ancient and modern, differ as to the probable
signification. Gesenius and De Wette interpret it, "with the voice of virgins, by boys." Others derive the word from a different Hebrew root, and interpret it as indicating that the Psalm was a funeral ode.)
(Supposed to be a musical term to guide in rendering the
song. At the close of the chapter, the author refers the ode "to the chief musician, on my stringed instruments." The term may suggest the movement in interpreting the music set to it.)
(Seems to indicate the manner in which these Psalms were to
be rendered. Kimchi, Tremellius, and Eichhorn render it "hexachorda," that is, that in singing these Psalms instruments of six strings were to accompany.)
