1-а хроніки 15:20

And Zechariah, and Aziel, and Shemiramoth, and Jehiel, and Unni, and Eliab, and Maaseiah, and Benaiah,.... Who were eight of the second degree; Aziel is the same with Jaaziel, Ch1 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 Psa 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 Psa 46:1.

The bringing in of the ark to the city of David was a very good work; it was resolved upon (Ch1 13:4), and attempted, but not perfected; it lay by the way in the house of Obed-edom. Now this chapter gives us an account of the completing of that good work. I. How it was done more regularly than before. 1. A place was prepared for it (Ch1 15:1). 2. The priests were ordered to carry it (Ch1 15:2-15). 3. The Levites had their offices assigned them in attending on it (Ch1 15:16-24). II. How it was done more successfully than before (Ch1 15:25). 1. The Levites made no mistake in their work (Ch1 15:26). 2. David and the people met with no damp upon their joy (Ch1 15:27, Ch1 15:28). As for Michal's despising David, it was nothing (Ch1 15:29).

15:20 harps: Hebrew adds according to Alamoth. Alamoth is probably a melody, believed to be sung in the soprano range (related to Hebrew ‘almah, “young woman”).
