|12--14--15---17 is the only 4 note per string scale fragment that is possible to play because of the limits of the human hand right? (that riff anywhere on the fretboard of course). I mean, say you play that riff, where is it going to lead to because my hand isn't capable of playing any other 4 notes scale fragment naturally. .... Stretch your hand out between 6 frets and your fingers are naturally going to fall on those frets (12,14,15,17 if you start on 12). Any other finger position isn't right.

...I guess once I get done that 4 note per string riff I've got to move onto 3 note per sting riffs because no other 4 note per string riff is possible or works in the same minor scale.

Actually, if I move that up a string it works but I'm playing the same note twice. Does anybody actually do this G.D. 4 note per string crap?
