> Many folk musics have independently arrived at the pentatonic The way I had the pentatonic scale explained to me (embarassingly recently) explains why this is so. If you take all the chords of a given key, and then examine all the notes, and remove any note that sounds discordant with any chord of the key, the notes that remain are the notes of the pentatonic scale. (That's not 100% true, but it's close enough to true for rock 'n' roll.) What this means is, if you have a backing track that sticks to chords within the key, you can kind of noodle around in the pentatonic scale however you like, and it'll sound alright. For guitarists, this is like adding training wheels to your bike... suddenly, you're effortlessly making music, without crashing and burning, and all you're doing is sticking to the pentatonic scale. (Yeah, there's targeting chord tones, and following the changes, etc. but for a beginner/intermediate guitarist, the pentatonic scale is magic.) Before youtube, the above information was rather hard to come by, I found. I played guitar for approximately 30 years before figuring it out via to youtube. I made a youtube video[1] covering what I deemed to be the salient points... I'm not aware of another single youtube video covering all these points, (though all the points are covered by many combinations of other multiple youtube videos).
