The guitar is a remarkably hackable instrument for a million reasons that will be revealed to you as you spend more time with it. As you go along in your journey you’ll find a million shortcuts and fun ways to learn fast. I’ve rarely heard any of this stuff from guitar teaches, so beware, trust your instincts, and learn from people who can show you where you want to be.
Because people learn in a variety of different ways, the flexibility of the online guitar lessons that you choose will be important. You may prefer to progress through a series of programs or you may want to jump around and pick whatever interests you. Not all online guitar lessons work in the same way, so you will want to consider which programs offer the best “fit” for the way you learn best.
