Y'know, I was out strimming (some might say gouging) the endless fields that masquerade as my garden, with a petrol powered 'scythe' and I got to pondering important stuff - mainly imagining what would it be like to have a zero-turn ride-on mower instead of a crummy strimmer! Eventually the constant coarse buzz of the engine led me to think... are minor 3rd (C system, B system etc) modes easier to play in than 5th modes, like Stradella bass or Quint? Now, to be fair to you Ben, I think yes, there could be times when this happens. Say a person takes up the accordion to primarily learn free bass and is trying to study both Stradella bass (a 5th system) at the same time as free bass (usually minor 3rds) - I think there may well be times where it's easier to play music with a well crafted free bass line than a Stradella bass/chord vamp or bass run.
However, my experience with the accordion has been slightly different to the possible scenario above, as I decided to take up free bass after playing Stradella for many years. In my situation I wanted to build upon what I already knew, rather than learn a new system from scratch. That's why I chose Quint (5ths) over minor 3rds. I remember the time I first discovered there was a free bass system that was closely related to Stradella bass and I was delighted! However, I am aware that it's not the mainstream option at this time, apart from pockets of Quint interest in Italy, America and New Zealand etc. Though it's not at the height of its powers any more (this ain't USA circa 1975) I'm happy to keep going with it as I think it works well for me. In time I'd like to add a chromatic free bass accordion too, but that will have to wait. I think Quint PA and Chromatic button converters are fundamentally 'different' enough to be worth trying to learn both and hopefully gain the best of both worlds.
I agree these very grand organ works aren't really necessary - I was mainly demonstrating that some accordions do go down as far as low C1. Grayson Masefield is a terrific accordionist though.
Thanks for sharing the Bach recording by Joerger - marvellous music. We need more of this type of music!
By the way, thanks for sharing your Scarlatti recording on an earlier post, it was great playing and very nice music! I think I rather like sonata K9 also...
