Realtime in-person lessons vs YouTube videos has been a talking point for some time now. There are many guitar tutorials on YouTube. There are some fantastic players, but far less are good teachers. Furthermore, YouTube is a one-way exchange of information. It is impossible to get feedback from a video and feeback is exactly what you need. In addition, aside from developing bad habits, or plateauing, you can learn a song the wrong way from YouTube and play it that way forever without realizing you are doing it incorrectly.
In actual lessons, an experienced teacher interacts with you and guides you as you take every step forward. Miami Guitar Workshop devises a program that is customized to your goals and learning style; your success is guaranteed.
