Fun fact I learned about the saxophone. No matter what size you use (alto, tenor, baritone, etc.), they’re all laid out and played the same way. In other words, if you play the tenor, you could pick up any of the others and the keys will all be in the same place, just maybe with a slightly bigger or smaller spacing. So if you’re familiar with only one, you could just start playing the other versions of a saxophone in very short order.
