Making music can be tough when you don’t know how or where to begin, but luckily, musical staples like blues scales are here to help.
From catchy pentatonic blues scales to attention-grabbing blues notes, blues scales have the power to make music more memorable and engaging.
In this guide, we’re breaking down the world of blues scales. We’ll show you what they are and how to use them to liven up your music.
What is the blues scale?
A blues scale is a six note scale based on the major or minor pentatonic with added chromatic “blue” notes. The blue notes are ♯ 4/♭5 in the minor blues scale and ♭3 in the major blues scale. The more common minor blues scale has the semitone pattern 1-2-♭3-4-♭5-♭7, and the major blues scale has the pattern 1-2-♭3-3-5-6.
I’ll go through and unpack that to explain exactly how blues scales work—and how to use them in your music.
