Problem with absolute music: 

music finds meaning rthrough association

Psalms- worship

Song of Solomon- wedding

Military- Moses and Miriam

Music with the spiritual realm- Elisha

Soothing Music- 1 Samuel

Teaching Music-Ephesians 5:18-20

Directly related to "teaching music" 

Both Ephesians and Colossians encourage Christians to neglect the ways of the world and turn to the encouragement and edification of music. Factors that alter the effectiveness of worship music are place, type, style, lyrics in relation to theology... The role of music plays an important role in "church life" and can be used for spiritual revelation, meditation, and edification. 

As worship- 2 Samuel 6:14- David danced before the Lord

As seduction- Salome before Herod

As military victory- Exodus 15:20

As Heathen worship- Exodus 32:19

As Cultural expression- Judges 21:19

Cultural dancing- expression of pride in one's culture

Religious dancing- discouraged in some churches. However, much like music, it is an expression of one's love and worship of his or her Lord and Savior, Jesus Christ. 

Social dancing- school dances, parties, weddings, ect. Often a celebration, but sometimes looked at as "inappropriate" by some Christians.

Seductive dances- Considered "immoral" outisde of a marriage relationship. 

All problems with dance are considered scruples within Christian society since there are no black and white rules in scripture.
