I have begun an improvisation learning method which begins with memorization of five patterns. I have worked on the patterns in the following ways: devoting one day to one pattern (playing all the way through the pattern ascending and descending at least 100 times throughout the day) and playing through each of the patterns one after another, then playing back through them each to the beginning. I have used a metronome sometimes, sometimes without. what I haven't done yet is work through each pattern from 1st position all the way up the neck and then back down, I wanted to get familiar with proper fingerings both ascending and descending. then I intend to work through all positions up and down at each fret all the way up and down the neck. but will this result in true mastery of the patterns? my friend who turned me on to this method is a very advanced player and he told me it took him about a year to master the patterns. actually, i'm not sure he means he took a year on the patterns only, or just the first lesson, which is learning the chords that work with the patterns. I would like to read anyone's ideas on how to gain the "absolute mastery" (well, honestly, is there really such a thing as absolute mastery?) of this material. will it take 10,000 hours? i'm pretty old, that's a lot of hours. the thing about, and why i'm asking for your thoughts and experiences, is that it is very easy to simply sit here and look at the page and mindlessly blow through the patterns. but I question it's effectiveness.
