Before I was a cartoonist, and even before my first day job, I was a musician. In fact, I went to college and got my music degree playing the trombone.
I was a fairly good jazz trombonist and even played professionally for a very short time before hanging up my mouthpiece. Which means that I’ve spent a lot of time with microphones. And as I’m sure you ‘ve experienced, there’s no worse sound on the planet than that squealing microphone feedback.
Of course, feedback also refers to getting information about how people feel about things.
So, being a cartoonist, you add a little positive feedback, a little negative feedback – and you get a business cartoon like this.
