Electric Bass: B Natural Minor Over the Changes
Where B Natural Minor lies at this seat, and what a chorus takes out of it.
B Natural Minor runs 7 notes to the octave, laid out here on EADG with every B flagged. Mid-chorus the pattern is not what you need; where the root is when the chord changes underneath you is.
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.
The electric bass can hold a note long enough for it to be heard as a choice rather than a step, so a scale here is read for its strong tones first and its passing tones second.
Play it slowly against the audio until it stops being a shape, then put it over two bars of a form and let the chord tones decide which of the notes you actually keep.
