I have returned to classical piano at 70, having reached RSM Grade 5 as a youngster and have been happily playing Clementi Sonatinas on the way to some easier Chopin, Mendelssohn etc. Until I went on Youtube and realised the professionals were all playing Clementi at breakneck speed! I realise that at my age there will be some physical and mental limitations on how fast I can play, and I am only playing for my own enjoyment so it doesn't really matter, but my question is whether these Sonatinas were really composed to be played so fast? To be honest, sometimes it seems to me that they are spoilt by this breathless pace which can blur the fastest parts - but that might just be sour grapes! Would welcome opinions on this; as I play and learn on my own, it can be hard to know what I should reasonably be aiming for. Thanks.
