Crash Course In Guitar Theory!

This is the basic twelve bar progression in "E" major, with scale fillers.

Notice that some scales are shorter than others. This is because of the timing that it takes, to play each scale. Notice that in the first measure, the Ionian scale contains, 16 notes. That is equal to four sets of four notes. This works fine after playing the "E" chord four times. The same format applies to the "A" chord. The Lydian scale, after the "A" chord, contains eight notes or two sets of four notes. This works fine, with the playing of two "A" chords. The same format applies for the rest of the progression.

There are endless different ways to write songs. The best way to write a song, is by experimentation and listening. Use the twelve bar progression as a foundation, then build around it.

There are no real rules, just a few examples of what other people have done. If it sounds good, then it's probably okay.

The next few chapters contain alternative chords, scales, arpeggios and approaches that are usable as substitutes to the ones already discussed. This will give the guitar player an even larger amount of possibilities.
