Think of 10 sounds from highest to lowest, and describe each object that you hit. What is its shape and what is it made of? Then describe how it sounds to you. Does it transmit sound well? Does it absorb sound? Is the sound loud or soft? Is there a “ring” to the sound? Does it sound like a “thunk” or does it sound like a drum? PS: I don't have 10 unique things, so I basically can't do it.
