I love Bach music but as far as playing his works I didn't get very far as of yet. But I tried to explore his legacy many times. The first attempt was a piano transcription of his Toccata and Fugue in D minor (BWV 565, it is written for organ not piano, what my daughter recognizes as the music from Paratroopers, an ancient computer game). I learned that piece about half way through and got stuck in the fugue. Compared to the more familiar (to me) Romantic composers, Bach with his polyphony turned out to be very difficult for me. The difficulty is not really in technique, but rather these voices do not fit in my head, I can't memorize the text if there are more than two voices. And of course his demands to rhythmic clarity are more than I can currently manage. Later I tried another Toccata (in C minor, BWV 911) but it met the same fate - the moment he added the third voice I got stuck (but promised myself that I will return to this when and if I grow sufficiently, because I like this piece so much).
I also tried to play the Inventions in the hope that it will teach me to work with polyphony but I don't particularly care for them musically, and I abandoned this project after a couple of months. But quite recently I decided to return to this step-by-step approach, but this time I took the first book of the Well Tempered Clavier.
So far I've learned the first C major prelude, skipped the first fugue and am now struggling with the second C minor prelude. I got a very good edition of the text, it has lots of interesting details, look for example how the modern texts are put together from various historical sources:
Turns out there are many disagreements about what Bach actually wrote and what was added later, there are various conflicting schools of thought... This even goes for the first prelude which is probably one of Bach's best-known pieces, apparently there are several measures in the middle which are not fully authentic... but I play those anyway:
Also, for a long time (probably three years at least) I play a fragment (Gigue) from the first B flat major Partita, this piece is very difficult for me but I really love it. You will briefly see the sheet music at the beginning of the video, and please note that there are no indications whatsoever regarding tempo (apparently everybody is expected to know how a Gigue should sound?), nothing about forte and piano, let alone the fingering and even which hand is supposed to play what (but you have to change the hand that plays the melody at least twice). So I had to learn it by example, and I used a recording by Angela Hewitt to guide me. She does an amazing job of it but plays it at least twice as fast as I can even in my wildest dreams, so she can afford not to use the sustain pedal while I'm forced to use it to connect the melody notes that keep jumping up and down (just look visually what the right hand has to do here). Without pedal it sounds even worse... but of course the pedal muddles the contrapuntal structure because the harmony keeps changing but the pedal is not quick enough to follow. So, as I said already, Bach for me is very difficult but I keep trying...
