let me be honest. i find the 5 patterns a much easier way to remember how to play scales…but others suggest the use of TetraChords. especially jazz peeps. and they know a lot of stuff…
so maybe they are on to something….either way…the more ways you know a scale, the more likely you are to remember it! it may also help you create some cool runs. and they can be fun to play once you memorize them.
Tetra(4) Chord – means that you play a pattern of the 1st 4 notes of the scale, then you can shift up 2 frets and play that pattern again and that will be the complete scale. so, you only have to memorize 1 tetraChord (series of four notes) shape per scale pattern.
let me tab it out, play it and you will see the simplicity of it all…remember it’s broken up into 4 note patterns.
middle, pinky, index, middle, [shift]
——————————————————————————
——————————————————————————
——————————————————————i–m————
—m-p-i–m————————————m-p————4-5————————
———2-3—-then shift up two frets—-5-7———————————————————–
—-3-5————————————————————————-
once you get down with that first octave, you start over on that note to continue into the next octave…AND, you have to shift on the B string…
middle, pinky, index, middle, shift m p i m

the one above is in G major – starting at a point that resembles, pattern 4….
now, here’s one with the same starting point as pattern 3, in A…

summary:
memorize how to play scales using tetraChords [series of 4 note patterns] starting in 5 different positions. you will get to know the neck better and have a new angle with which to approach your playing
