I know, long time no see. I will fail gloriously this year as well, but for the best of reasons. My teacher told me that it was time for a challenge, and I immediately said: Bach's 6th invention. Since then, I have spent about 90% of my practice time with this piece. My! This piece messes up my mind so badly. But it is also great fun.
But I hardly spend any time practising my other pieces, and as for quick studies, I have no time for them. ๐
