So, last night, after watching that video from samuraiguitarist about efficient practice, YouTube suggested another video from a Danish guitarist named Claus Levin. It was about learning scales faster. I watched it, and a second video from the same author showed up in the related videos, also about learning. I found it fascinating. It proposed a different learning/practice method from what I’ve seen before – basically asking us to practice in short bursts and then try to forget what we’ve practiced.
The idea is that when we practice, we’re taking information into short-term memory. By forgetting it and relearning it, we’re telling our brains that this is information that we have to relearn repeatedly. In order to better support having this now frequently-accessed information at hand, the brain then moves it from short-term to long-term memory, where we have it forever. Claus goes into more detail, starting with a human brain/computer cpu & memory analogy that makes much more sense a few mins in.
The other video is about practicing scales by taking the notes and learning them in a random order or pattern, instead of the usual method of running up and down scales from lowest note to highest, or vice versa. In a way, its similar to improvisation. Its goal is to leave us with usable knowledge of the notes and their locations and functions – essentially enabling fretboard freedom. Claus labels the standard method as learning sequential information. What he suggests, instead, is more akin to learning a scale pattern and then using it to create licks (or for us, basslines). Its more functional and musical.
