Re: how do i use scales to make music
First off, scales are great as a vehicle for tying the neck of the guitar together. However, scales can be quite limiting to a player as they tend to lock you into patterns that through force of habit can be difficult to break out of. Just ask any of the thousands of guitar players that find themselves locked into the Major/Minor Pentatonic hell that one often finds themselves confined to after years of playing rock or blues. It can become quite difficult to rewire your brain after years of drilling a bunch of scales and modes into your head.
Ultimately, this leads to a lack of creativity! Unfortunately the poor victim of "scaleitis" erroneously thinks that the cure is the study of yet more scales! Or even more hilariously, they attempt either to discover or create new scales! :crazy: Learn to use scales and modes for what they are good for! That is learning to find key centers over the length of the fretboard.
The bigger question is, "How do you go about creating melodic ideas?".
What you really need to study is harmony and voice leading! Many of today's guitar masters are quoted as saying that they study more horn players than they do other guitarists. Why is this? Because, ironically, horn players spend more time studying harmony than do guitarist and players of other polyphonic instruments. Horn players cannot play chords the way we can. Therefore, they spend a great deal of their time practicing and learning arpeggios on their instruments. Sadly, a horn player knows better how to dissect a chord into arpeggios and extended arpeggios than do guitarist having full knowledge of chords! :lame:
Guitarists cannot see the forest for the trees. They constantly ask dumbass questions like, "Which scales can I play against this chord progression?", when it is the chords themselves that hold the answers to the question!
On its face, the study of arpeggios looks simple in concept. Believe me it is not.
