If you practice guitar for 2 hours a day, you can expect to see steady progress in your playing abilities. This consistent practice can help improve your finger strength, dexterity, and speed, as well as enhance your understanding of musical theory and technique. It is important to maintain a balance between practicing new skills and refining existing ones, and to ensure that you are practicing effectively and efficiently during these 2 hours. However, it’s also worth noting that while regular practice is crucial for improvement, extended periods of practice can lead to injuries, so it’s important to listen to your body and take breaks when needed.
