Have you ever noticed how music enhances everyone's sense of togetherness?
Think of that famous scene near the end of "It's A Wonderful Life" where everyone sings "Auld Lang Syne." Scene's like this impact viewers because they bring to mind joyful memories of singing along with friends and family. Who hasn't smiled while singing out loud to a favorite song while riding down the highway? Who hasn't had a sour mood turned around by singing a silly tune with a child? Times like this bring smiles to our face and draw us closer together.
The next time you are with a group of people, enjoying songs together, notice something else: the skill of the person leading the song isn't really important. No one seems to mind if the instrument is slightly out of tune, or the chords aren't played exactly right, or there aren't any fancy runs, bends, or riffs.
What's the point? For those of us who play an instrument, we need to stop being so self-critical and just play! Sure, you should practice songs well enough so that you are familiar with them and can jump back in if the group makes a mistake (like repeating the chorus). But once you have a bit a comfort, share your talent with others. Play! Hand out lyrics. Encourage everyone with a smile. You'll have fun and draw closer to your family and friends.
For those of you familiar with God's Word, none of this should be surprising. There are nearly 190 verses which link song with joy, and the vast majority of them refer to groups of people.
