One of my grade eight pieces that I’m working on right now is Clementi’s Allegro con brio, Sonata in B flat Op 24. I think it is a very beautiful piece and I am thoroughly enjoying practising it. I found that some pieces in it are difficult to play fluidly, and that my fingers somehow seem to get stuck, or freeze at certain parts. I have found some lovely examples below from you tube of how the piece should sound.
