I am from Berlin, 50 years old and I think I am an intermediate concert guitarist. Currently I train and play the three Sonates from Anton Diabelli Op.29 (1,2,3). Especially the 3rd Sonate is a masterpiece and I am able to play it quite well (I think ).
I learn a lot by studying tabs in addition to the original notes but I also have a look to YouTube quite often, just to get inspired by the masters (e.g. Marcin Dylla) how they play and how the melody should be.
Hope to get some more inspiration here in the forums!
