No matter at what level is your ability to visualize, it can develop in a daily work. Start by imagining you where you practice your instrument: what it looks like, smells, how you feel when you would normally enter this room.
Imagine yourself trying to perform simple extracts on the guitar. Imagine the sound it produces, acoustics, resonance. To develop this ability to visualize, you should work on it 10 to 15 minutes a day.
For example, you can train to see yourself going up on stage, play your repertoire with pleasure and visualize the warm welcome of the public. You can also visualize a difficult passage seeing you be successful in your head, the brain then lower the psychological barrier that was created earlier.
In addition, you can train yourself to see your fingerings and your scores to accelerate memorization. You can train yourself to relive a performance that was a success for you. Imagine staying focused, despite all possible distractions. Imagine reacting in the right way.
You can help you overcome your blockages thanks to visualization. The secret is in regular training.
