Give everyone (including yourself) a few sheets of paper and crayons or colored pencils. Tell your crew that you are going to play several different songs and, while each song is playing everyone is to draw how the music makes them feel.
For the first song, you might put on something slow and mellow. For the second song, crank up a tune with plenty of loud guitars. You may even want to try something fun like Irish folk music.
After you've finished your pictures, compare the mood of each piece. Can everyone see how the music affected their feelings?
