thanks, I will read it and send it to my teacher as well!
please show me the Mondschein Sonate tabs, you mentioned. I do have the piano notation myself, though.
in some parts of Prélude No. 1 by Villa- Lobos these things are solved by simultaneously playing 2 notes with the thump, or a rapid arpeggiated 'p p i m a'.
but I am highly interested in this topic!
