I really don't like it at all! Don't get me wrong, as an engineer I think it's a very exciting project. But as a guitarist, who spends a lot of time teaching others how to play, I could not think of a more misguided idea of what the instrument is about. gTar works on the assumption that playing the guitar consists of putting your finger on the right fret at the right time. Imho this is as wrong as assuming that programming consists of pressing the correct keys in the right order. (million dollar idea: Teach you programming by putting LEDs on your keyboard! $599 only). There's a common misconception that learning to play the guitar consists of learning where to press; after all, isn't this what tablatures are all about? I tend to put much more emphasis and practice on right-hand techniques. Other comments in this thread speak of 'early reward' or fast gratification; stubbornly trying to bend your left hand in unintuitive positions while your right hand cannot cope is NOT the answer. Side-note for beginners wanting to learn the guitar: Learn a few chords you don't need a lot of them, then practice right-handed techniques (you can find plenty of examples off Youtube) religiously. Early mastery of this would rapidly give you comfort around the body. You can then get your gTar, read your tabs, or do things correctly by watching videos of your favorite artists and learn slowly to reproduce their songs. Again, the engineer in me thinks this is an amazing project. However I would never recommend it as a guitar teaching tool.
