Guitar

The guitar is a highly imperfect instrument if compared to something like a piano, which is much more mathematically elegant.

However, Ciro Santilli just loves this imperfection for some reason, especially in the case of the electric guitar.

Bending, sliding and strumming just feel to good to not have.

And Ciro sucks are doing things in parallel, so the more single threaded approach of the guitar fits his brain/abilities better.

For those reasons, the electric guitar is Ciro's favorite musical instrument.
