Have you played a chromatic scale on a bassoon? It is hellish – all thumbs and embouchure – and for my teenaged self it was my driving goal. Every day I practiced. Finger blisters, facial tics, and bleeding lip (I wish I was kidding) would not deter me. And a few weeks later - booyah!! Not only could I play a chromatic scale, but play it well and with ease, and the proficiency I developed in my practice elevated my creative technique.
