I've never been in that situation before, but I was locked up, and the only way that I still practice was I drew a scale and label the keys on the paper, and being able to play in every key helped me to write out chords and runs, in different keys, even when I was tired and frustrated because I didn't want to be there, I would study and practice mentally, then when I returned home, God had bless me to be on a level that noone could understand becuase it was like I was the only one there, this allowed me to bring our music ministry to up. Now no more struggling in the music dept. Thats what God did for me, maybe my testimony can help you understand. He took me from my comfort zone, to bring me down, build me up where I wa suppose to be,
