1.) OK, so Im reading something about an Intro to Scale and Chord Theory, and as it askes me to look at Cmaj,(C-D-E-F-G-A-B-c) starting with the E string, they say the scale in tab form is: G: 2-45 D: 23-5 A: 23-5 E: -3-5 now if this is the Cmaj scale why does it start at G on the E string and not on note C?? Same thing with its example of the Dbmaj scale starts on G#/Ab....I dont get it! Why doesnt it start on Db?? 2.) my second Scale question is why are there 5 different scale patterns for major, minor and minor pentatonic ?????
