I've played most of the band/orchestra instruments at one time, I started on Alto Sax, then Baritone Sax, then Bassoon while playing Bass Guitar/Piano in Jazz Band. I played Sousaphone and Tuba in Drum Corps and Bass Viol in orchestra, I've filled in as bass clarinet or bassoon when needed. I also play guitar and violin and recently started on cello last year.
There are very few of us who understand the difference between a tuba and a sousaphone. I marched in Drum Corp with a TUBA and HS Marching band with the Sousaphone.
