Bach definitely. The pieces are always great for playing as well as listening. About 4 years ago made a recording of the Contrapunctus 1 from Art of Fugue on the keyboard at home set to organ for the PW Online recital. I still listen to recordings of the piece including my own. When Bach composed his last set of canons & fugues (BWV1080) he didn't specify the instrument. Over the years these were performed as piano solo, organ, strings ensemble, brass ensemble.
The last piece is my arrangement of #78 final Chorale from Matthew Passion (BWV244). Interesting that the piece is in Cm but notated with 2 flats in the Key Signature instead of 3. Sounds sad (melancholy) but still optimistic. Has nice sustained notes. The original performance was with 2 strings ensembles & 2 choirs on opposite sides of the St. Thomas Church in Leipzig. The keyboard accompaniment was an organ. My version is for piano with pedal to sustain longer notes.
A few months ago I found a piano version of the Haydn "Surprise" Symphony 94 in G. Right now I'm just doing the Andante in C than the other 3 movements in G. It's a piece that has arrangements for beginners & intermediates with just the first section in C major. And the middle section goes into C minor and has the fast 32nd note runs. I'm not able to play the runs at lightning speed. Even at a slower tempo the piece is fun to play and gives me a surprise every time.
