Just focus on listening to something. It doesn’t need to be music, although in my experience, music has a special power as typically, it is carefully crafted and shaped by humans. But nature or random sounds can be very fun as well.
Now close your eyes, and with the sound on, try to imagine what kind of shapes do those sounds have, and what colour. Imagine the body and movement that each instrument or group of instruments form. And stare at those inside of your mind.
Do it for 15 minutes. What do you feel now?
