I like the passage starting at 6:20.
19:02 Bartok influence?
The benefits to your playing from lessons and practising on acoustic instruments is evident. You are achieving a more supported and fuller tone from the piano. Chord voicing is improving with emphasis on the melodic and bass notes when appropriate.
No, I had no clue! I've never listened to Bartok. I somehow come up with these kinds of melodic and rhythmic ideas, and I think I always have to some extent. I often wonder whether someone has done them before. Could you link a Bartok piece which sounds similar? What makes it sound like him?
One of the things he is known for is collecting and studying folk music. That melody struck me as something reminiscent of his tunes.
