I'm learning this beautiful piece. Technically it is generally quite easy to play, apart from what are no doubt the well known problem patches - starting with the first entry of the main melody!! There is no other way to play these passages, you have to just bend the fingers where they don't want to go and press hard as hell on the barre. Occasionally (once or twice so far) I manage to get all/most of the notes sounding clearly, giving rise to an audible 'Yes!', but most of the time it's an ignominious 'phut' instead of a note on the top string.
Any suggestions/commiserations welcome - I'm sure there's someone out there who has been playing this perfectly for years...
