Continually encourage and inspire your children to do their best and to be their best. Listen to them play their instruments. Get involved! Find out what music they like and want to play. Do they create and compose music of their own? Do they play by ear? Why do you want them to play an instrument? Why do they want to play an instrument? Tell your children how wonderful they are! Make music with your children!
