Hi, any suggestions for good educational guitar books that are still useful and entertaining to read between lessons when you don’t have your guitar with you ie like during a commute? Obviously this rules out any book which gives a detailed step by step guide on fingering, chords, etc. but I’m looking for more of a general overview/ tips and tricks / motivational / things to think about before your next lesson type book which is still a good useful read without having a guitar in front of you to practice on. Basically something that will help me become a better guitar player mentally without having the guitar in front of me to practice on. Does any such book exist? Not interested in biographies.
