1. Technique: check your posture. Make sure the guitar touches the middle of your chest! Left hand thumb stays flat on the sticker!
2. “Oh Suzana” move away from the paper. Practice memory! Go line by line and make sure to play good at least 3 times! Good means: Notes/Rhythm/Fingers.
Try increasing the speed gradually. It will help the memory.
3. “Prelude No. 9” great progress! About the gaps by preparing the next finger ahead of time. Go a little slow first.
