Progressions in G — Bass (5-String)

Every chord the key of G contains, seen from the bottom: roots, distances, lines.

G major harmonizes to G – Am – Bm – C – D – Em – F#°; G minor to Gm – A° – A# – Cm – Dm – D# – F. To the rest of the band those are chords — to you they are a map of root movements, and each one links to its Bass (5-String) page with the tones to fill the space between roots.

Loop the workhorse moves — I–IV–V, ii–V–I, i–VI–VII — in G until your hand knows the distances, then start dressing the roots with fifths, octaves, and approach notes.
