Guitar, particularly jazz using The Jazz Guitar Handbook by Rod Fogg. Great book to get into playing jazz feeling stuff. I have a fantasy to do trios/quartets, but not yet at a level to play with others. (looking for any books/advice for next step). Korean, particularly the listening part. Listening and parsing at the same time is really tough. Does anyone recommend italki?
