You show up at some dingy, uninspired facility, maybe the back room of a music store or at best, a thrown-together cubicle with a “music school sign” out front.
The teacher might be a cool person, but they probably don’t really have a plan for you. They work on songs with you and at the next lesson, it all starts over again. They don’t have a long term plan that matches your long term goals.
After the lesson, they scribble down illegible notes on a crumpled piece of paper, or in the margins of an unlabeled, handwritten guitar tab that looks like hieroglyphs – and you are somehow supposed to decipher and practice from at home. All of this adds up to an uninspired, disorganized, and inefficient lesson experience.
