C Aeolian — Bass (4-String)

The C Aeolian scale runs 7 notes per octave in the modes family. Below it sits on the Bass (4-String)'s EADG strings with every root marked, because a bassist reads a scale map as a set of targets around the root, not a row of dots.

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.

In fourths tuning every pattern is movable: learn the shape once, one finger per fret, and it works from any root on the EADG neck.

Walk it slowly against the audio, land each root on a downbeat, then take it to the progressions in C and let the scale turn into lines.
