I’ve come across in studies and occasionally pieces repeated patterns that are various chord inversions usually within an octave, that have fingerings printed as 4-2-3-1. (e.g., E-C-G-topE, or similar). My natural instinct would have been to play them 3-1-3-1, which is a million times easier, louder, and smoother sounding, but I am sure that those are the suggested fingerings for a good reason, so I am persisting with it, though find it quite hard with small hands and some weak fingers!
So I’m wondering what the advantages of the 4-2-3-1 fingering is and why/when you would choose that in a piece. I’m guessing that because it is a repeated pattern, it helps keep your hand in vaguely the right position for playing it again quickly. Is that right, or are there other/more advantages?
There are a few patterns where I can’t reach the chord that way, so after several bars of a chord shape where I can, there will be something where there’s a stretch of, say, a fifth between fourth and third fingers – like G-E-D-G, and I have to go back to 3-1-3-1 or 3-1-2-1 depending on the exact notes. At the moment, those bars always sound better than the ones where I’m trying hard to do the recommended fingering. I realise that recommended fingering is just that, recommended, and doesn’t need to be followed religiously, but given that this pattern comes up frequently, and that there are studies devoted to it, I’m fairly sure that it’s been marked for a good reason and that I should try as far as possible to learn to do it. So I don’t want to give up too soon.
