I would use the fabric as a large panel and then use a neutral color (blue or tan) in large blocks around it and applique some of the instruments over the blocks and applique some of the words. I would use the fabric with the words as a wide border. I doubt if the boy is interested in the pattern but will fall in love with the visual of the intact instruments on the quilt. I would make matching pillowcases for him. instruments with a border of words or the neutral color with a border of words.
