A deliberate practice app for guitar players who want to level up

Total noob as in yet to buy your first guitar? I’d highly recommend taking offline lessons from a local guitar teacher, at least for a few months. Some things are difficult to unlearn and relearn later on. This app can be used to practice the lessons the teacher would give you.

If the place where you buy your guitar doesn't have lessons then buy your guitar elsewhere! There are music stores all over and nearly all of them have guitar teachers on staff - often the owner teaches guitar himself. If you want to play something weird (harp?) you might be stuck with online only lessons buying something without playing it from the internet. However most instruments have a local music shop and you should buy from them if possible. Note that guitar the patterns seems to be lessons are in the store you buy from. Piano you are generally better off with an unrelated teacher, and violin seems to be always unrelated private lessons - all are okay.

I would consider a teacher important enough that I would borrow/rent an instrument to try out teachers and only after you find a teacher you like buy. It is typically better to play an instrument you have never heard of before taught by a teacher you "click" with than buy the instrument you think you want but not find a good teacher.

That said, online lessons are great supplements to your teacher. And if you are broke (between jobs) often cheap. Sometimes online lessons can teach you things that your local teacher cannot (as opposed to will not because you are not ready). However the local teacher will also correct things that you will lie to yourself about.
