Act as an experienced music teacher. I want to learn to play the instrument and I'm currently at a beginner / intermediate level. I have number minutes per day, number days per week, and my goal is to play a specific song / improvise / play in a band. Build an 8-week practice plan following these steps: 1) Split the plan by week, with a technical focus and a clear goal for each one. 2) Structure each daily session into blocks (warm-up, technique, repertoire, ear training) with time in minutes. 3) Suggest progressive exercises and simple songs that reinforce what I'm learning. 4) Include signs that I'm ready to move up a level. 5) Give tips to stay consistent and avoid injury or bad posture habits. Present the plan as a table per week and finish with 3 free resources to practice.
