My son likes playing tennis. In winter season they have their training at the tennis hall. I brought them with the car. Because it was so cold outside I waited and watched them. Hitting the ball inspired me to this song.
My son had to create a presentation about Jazz in school. On one slide he listed the common instruments like trumpet or clarinet. To pimp up the slides, I recommend to add the sounds of the listed instruments. In GarageBand he found a nice autoplay chord for the clarinet.
