At primary school, I learned to play recorder (along with most of my generation). I learned by descant and treble recorders, which have slightly different fingerings (or rather the same fingering produces a note which is a fifth higher on one than the other). This stood me in good stead for the clarinet, which I picked up at secondary school – this usees treble recorder type fingering in the “lower register” and descant type fingering in the “upper register”. There’s a few weirdo fingerings in between (sometimes called the “middle register”), but they weren’t hard to pick up. After that I got a tenor saxophone, which made great noises, but was way too loud to practice in the house! So now I play a wind controller…
