CP,
Here is Strong's definition of the word translated "shouting" in 1 Chronicles 15:28.
From H7321; clamor, that is, acclamation of joy or a battle cry; especially clangor of trumpets, as an alarum: - alarm, blow (-ing) (of, the) (trumpets), joy, jubile, loud noise, rejoicing, shout (-ing), (high, joyful) sound (-ing).
I'll let you draw your own conclusions about what the author is trying to say here. I don't believe, however, that shouting is the most accurate translation. The context is that of a musical event. Shouting is not usually regarded as something musical (unless of course you want to consider rock and roll as music).
