C Natural Minor, Mapped for the Guitar

C Natural Minor runs 7 notes to the octave, laid across this seat's EADGBE fretboard with every C marked. A blues phrase is short and keeps coming home to one pitch; the marked notes are where it comes home to.

The standard natural minor scale — melancholic, introspective, and deeply emotive. The most common minor sound in Western music.

Heard in: Pop, rock, classical, metal — the default minor sound of Western music.

On the guitar a scale is mostly raw material for bends: a note a fret or two below the one you want, pushed up until it sounds right against the chord, which is how a fretted instrument reaches the pitches between its frets.

Whatever scale you start from, the blues bends it: the third and the seventh get pushed flat, or somewhere between flat and natural, and that pull against the chord underneath is most of what the idiom sounds like.
