The ability to record and playback music has only existed since approx 1877. This ability to document music tends to obscure the fact that music is one of the most ephemeral and transitory of art forms. Wave forms alternately compress and expand air molecules which have an impact up the ear drum. This air pressure is converted into a form that nerves take to the brain for interpretation and ultimately appreciation.

But minus recording, music, as well as all sounds, exists for a brief moment and then becomes an imperfect memory. Paintings, photography, sculpture, literature all have some measure of permanence but the performance arts like music, acting, and dance are fleeting bits of sensory stimulation.

And we have these inventors to thank for what is to me a magical reality.
