Original four-bar walking-bass progression
| Bar | Chord | Right-hand notes | Lowest left-hand note | Why the bass matters |
|---|---|---|---|---|
| 1 | C | C–E–G | C3 | Starts the descent |
| 2 | G/B | G–B–D | B2 | Moves down one semitone |
| 3 | Am | A–C–E | A2 | Continues down one whole step |
| 4 | F | F–A–C | F2 | Settles lower |
The first three bass pitches move C→B→A; the fourth moves A→F, a larger interval. If you want an all-stepwise line, experiment with F/A in bar 4, but that changes the written arrangement and would be your own variation, not the exact given study.
Compare before and after
Play root-position basses C3–G2–A2–F2 on successive bar ones. Then play the specified line C3–B2–A2–F2. Keep all right-hand chord qualities unchanged. The new second bass note makes bar 2 more connected even though the G harmony remains recognizable.
Keep changes clean
Use a new right-hand chord on beat 1, sustain through beats 2–4, and lift any sustain pedal around the next harmony. Avoid assuming G/B means you should hold two unrelated bass notes simultaneously. For any unfamiliar slash symbol, first decode its chord and bass separately using the symbol key.
A singing application
When supporting a vocalist, a descending bass can provide direction without adding distracting fills. Keep bass volume modest and listen to the top line. If the original singing key is too high, transpose the entire harmony and bass line together; see transposition.
