In Joyful Exuberance (David before the Ark of God returning)
In Celebration (various feasts)
In Warfare (the sending of worshippers ahead of the army. This one is hard to find so here is the reference for you: 2 Chron 20:20-30)
In Victory (Miriam the prophetess and the Israelite women)
Dance in the context of actual worship is performed by David in a linen ephod before the Ark of God. It was apparently an undignified spectacle in sight of everyone, yet the Lord delighted in David's heart so much that those who dared to criticize the display felt God's judgement. David is the only man mentioned in the Bible as a man after God's own heart.
Worshippers went out before Jehoshaphat's army "singing and praising" God to the detriment of the enemy whom God throws to confusion.
Dance (and flags as a visual tool, both beautiful and majestic) in worship are prophetic in nature.
The worshipper expresses what they are discerning in their spirit from God.
God speaks through people and through signs and symbols (see whole Bible).
The spirit of the born-again Christian is able to worship God in spirit and truth... the only worship acceptable to God (John 4:23-25).
Using our God-given gifts in general, in obedience to God, is an act of worship.
