Chords the Electric Bass Seat Reads Off a Chart
Every root, every quality — with the job each one does once the tune names a key.
Pick a letter, then whichever of 54 qualities the chart wrote after it. What comes back is the voicing plus the thing a chord chart never says: which degree this is likely to be, and therefore what the rest of the group is already covering.
The electric bass seat carries the amplified bottom — the same harmonic duty as the upright, played with a fingerboard that answers back and a sustain the room can hear over a backbeat. The chord tones are the same ones the upright would choose; what changes is that a note can be held through the bar instead of dying, so a line can lean on a chord rather than announce it.
Every shape is drawn for EADG across 4 strings, the open ones first and the movable ones up the neck after them, and each one plays back so you can hear the voicing before you commit it to a chorus.
