The pure chromatic guitar scale is all twelve notes, none are left out. On your guitar, this means you could play each fret on any given string and you’d be playing the chromatic scale all the way up the string.
Most guitar scales leave out a lot of notes from the chromatic scale, that’s how we get groupings of notes for each key. On the guitar, we don’t typically play the pure chromatic scale, but rather play a modified chromatic scale that makes more sense as it relates to the guitar.
In this lesson you’ll learn a “cheater” chromatic guitar scale from the A minor position. The reason it’s a cheater scale is a couple of notes are left out.
