If you are joking, then I have laughed and you can stop reading here. If you
are serious, there is an answer to your question.

The ball acts as a clapper and strikes the bat that acts as a bell. In a
bell, or the strings and soundboard of a stringed musical instrument, the
material is very important. That is because the sound passes through the
material on its journey to your ear.

In musical instruments such as the harmonica, the sound does not pass
through the materials in question on its way to your ear. In a harp, if the
reed is of a reasonably good spring material that will vibrate at the correct
frequency and amplitude, it will make the same sound regardless of material.
That is because the sound in a harp is made by the opening and closing of
the slot by the reed that modulates the airflow as occurs in a siren. The
materials of wind instruments are unimportant acoustically because the sound
is generated in a vibrating column of air and comes to your ear through the
air. The differences in sound of wooden and brass clarinets are
imperceptible in blind comparisons.
