A musician is a person who plays at a church. A M.O.M. is essintially a musicians boss. He is the leader of all musicians, choirs, etc. Makes sure all musicians know their music, choir knows there parts. A musicians/M.O.M. should have a good standing personal relationship with the pastor because they may often call on each other for various things. 9dont makes sense the two of you not on speakin terms and u really need each other). AMEN
