1- Learn scales, chords(arpeggios) on one string first. Learn the distances between the notes(numbered Intervals) as well as the notes themselves. Use the Nashville Numbering System. No matter what style of music you play, you must understand the basic’s of Chording, Melody and Harmony.
2- Learn scales, chords in as many positions as possible. Learn how to build them.What are the similarities, differences? How does the G-B hump effect them? Look at the Gootar color system.
3- Don’t try to play new material at full speed. Break riffs into smaller pieces and cycle them. Don’t rush, you will be able to play a piece faster in the long run, if you start of slowly!
4- Practice in your head without your Guitar. Being able to visualize a chord or riff, is the first step to executing it consistently or altering it.
5- If you are having trouble learning new material or techniques, sleep on it. The 1/2 hour before you fall asleep at night, is the best time to practice visualizing the fingerboard, chords, scales and patterns. Don’t count sheep, count frets!
6- Pay attention to how different chords, phrasings, intervals and tonal colors make you feel, (Maj-rising, min-falling).Even non-musicians understand Tonal Gravity.
7- Learn the cycle of Fourths and Fifths. They are called “Perfect” for a reason. You should always know where the IV and V are, in relation to the Root note. J Hendrix’s mastery of Fourths and Fifths is obvious (“Hey Joe” chord progression is a good eg) Interactive circle of IVths and Vths
8- Teach yourself, even if you are studying with a teacher. Try to solve problems with math, logic and just plain screwing around(Abstract Reasoning). Learning what you shouldn’t do, is part of learning what you should. Don’t be afraid to “Noodle” because you might hit an off note. Everybody learns differently. You have to develop your own sense of what works and what doesn’t. Link; https://gorehound1313.wordpress.com/2009/11/02/the-importance-of-being-a-self-taught-musician/
10- Practice pressing down on the string with just enough pressure to get a clear note, no buzz or trail offs. Avoid squeezing the neck, it slows you down and makes it hard to move to the next position.
