Music has transforming power and a unifying effect.  God created music.  Follow the leading of Christ and sing when the Holy Spirit leads.  Sing while alone, while hiking or driving.  You can always have a melody in your heart.  Sing in family devotions or impromtu sing-a-longs.  If you can play an instrument, use it to the glory of God.  If you have a music ministry, stir up the ministry by practice, hopefully, as a family.  

"Speak to one another with psalms, hymns and spiritual songs. Sing and make music in your heart to the Lord, always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ." Ephesians 5:19 & 20

Sing during times of fellowship with your family.  Don't fear to sing in the Spirit.  When the Holy Spirit moves in singing in the Spirit, give yourself fully to it.  

Exercise discretion in your music.  Satan's music can often be found where you don't consciously notice it, but it is perhaps most dangerous at this level.  You may find it in the background music on TV for instance.  If you listen to the wrong kind of music, it will harm your ministry.  Satan wants to use music against us to bring us out of the presence of God.  Satan does not care how badly you miss the mark.  He just wants you to miss the mark.
