‘ And David and all the house of Israel played before YHWH with all manner of instruments made of fir-wood, and with harps, and with psalteries, and with tambourines, and with castanets, and with cymbals.'
While the cart was making its journey it was accompanied by the ecstatic crowds, who played on all kinds of musical instruments before YHWH. It was the celebration of a great occasion, and there would be much singing and dancing. All would be filled with joy at the thought that YHWH's throne would once more be among them. David never forgot Who the real King was.
