Playing a musical instrument in a dream is the easy expression of your passions and feelings. Playing a xylophone represents harmony in expressing the individual areas of your life. If only one tone or one 'key' becomes the focus of the dream, you may be questioning your ability to get some aspect right so that your life 'plays in harmony.' A broken xylophone can symbolize depression. If you are dreaming about it - you might want to examine whether or not you are happy.
