Who were eight of the second degree; Aziel is the same with Jaaziel, 1-Chronicles 15:18 and Ben is left out, in whose room Azaziah, in the next verse, seems to be put; Ben is thought to be sick or dead before they came to execute their office, and whom the father of Kimchi takes to be the same with him who is expressed in the title of Psalm 9:1 which title is, "on Muthlabben", or the death of Ben: these were appointed to sound
with psalteries on Alamoth; psalteries were another kind of instruments of music; and Alamoth was either the beginning of a song, to the tune of which those instruments played, or the tune itself, and the note of it; either the treble or counter tenor, a shrill sound, like that of organs, which this word sometimes signifies, see Psalm 46:1.

Alamoth - Or, with Alamoth which is thought to be the name of an instrument of musick; or of a certain tune, or note, or part in musick. The certain signification of it is not now known; and the like may be said of Sheminith, 1-Chronicles 15:21.
