I know I've made a mistake in how I built my technique. Jumping back and forth from thigns that are too difficult for me, without thinking about how it was harming me. I went through Alfred's piano library and finised when I was 12.(then playing for 3 years). And jumped right tinto Joplins Maple Leaf Rag. It went well. Then learned a Hadyn sonata, which also went well. And then in order, Bach's English Suite A minor, The Magnetic Rag, Revolutionary Etude, The Cascades(Joplin again), and then Chopins 2nd sherzo, then Rach's Prelude op. 3 no. 2. I've now been playing for 6 years, and I realize I can no longer hide bad technique with good musicality(which is how I've been getting along even with competitions). I know I went wrong somewhere, but I was never instructed to do otherwise, I just kept going. I've now been advised to learn Mozarts Sonata K 545 and Beethovens sonata Op. 2 no. 1. It's, it's like I'm missing random bits of technique all over the place. Am I going on the right track with these new pieces?
