Private lessons allow the student to work at their own pace and have lessons tailor-made to suit their needs. The teacher can focus more on the individual student’s playing technique and style. The amount of attention focusing on each individual student is 100% which group lessons simply can not offer. Students can usually accomplish their goals or learn to play a song faster in private lessons.
Group lessons bring in the important aspect of joining fun and learning to play together as a team. As long as all of the students get along and are focused on the same goal, it can add an extra element of accomplishment to the proceedings. You may also be surprised at how much the students can actually learn from each other.
