Es scheint wirklich ganz leicht zu sein, wenn man sich nur auf sich selbst verläßt. Das zumindest zeigt der Artikel How to Play Guitar von David Fair:

I taught myself to play guitar. It’s incredibly easy when you understand the science of it. The skinny strings play the high sounds, and the fat strings play the low sounds. If you put your finger on the string farther out by the tuning end it makes a lower sound. If you want to play fast move your hand fast and if you want to play slower move your hand slower. That’s all there is to it. You can learn the names of notes and how to make chords that other people use, but that’s pretty limiting. Even if you took a few years and learned all the chords you’d still have a limited number of options. If you ignore the chords your options are infinite and you can master guitar playing in one day.

Als jemandem der der lautesten Band der Welt gegenüber sagen wir nicht ganz abgeneigt ist hat mir natürlich besonders der Absatz über die Lautstärke der E-Gitarre — und darin die Formulierung much higher reaction to effort ratio — gefallen:

I highly recommend electric guitars for a couple of reasons. First of all they don’t depend on body resonating for the sound so it doesn’t matter if you paint them. As also, if you put all the knobs on your amplifier on 10 you can get a much higher reaction to effort ratio with an electric guitar than you can with an acoustic. Just a tiny tap on the strings can rattle your windows, and when you slam the strings, with your amp on 10, you can strip the paint off the walls.
