Stepping
Chapter 10 — Part II, Motion: How Does the Bass Travel?
The Question
What makes a bass line sound smooth rather than jumpy, independent of where it eventually ends up?
The Mental Model
Stepping is motion by adjacent (second) intervals — a series of steps that produces a smooth melodic contour. It’s a statement about shape, not about destination.
That distinction matters because Stepping is easy to confuse with Connecting Chords (Chapter 15). A stepwise line can simply wander within one unchanging harmony, going nowhere in particular — that’s Stepping on its own. The moment those same steps are aimed specifically at landing on the next chord’s root as the harmony changes, the line is doing something more specific: it’s Connecting Chords. Every Connecting Chords route may use steps, but not every stepwise line is connecting anything.
Adjacent motion reads as smooth for a simple reason: each step asks the ear to recalibrate by the smallest possible amount, one scale degree at a time, rather than reorienting around a large jump. That’s a statement about how a line feels moment to moment, and it holds regardless of whether the line is going anywhere in particular — which is precisely why a listener’s instinct to hear purpose in a smooth line (surely it’s heading somewhere) is worth resisting. Panel A is proof that smoothness and destination are independent variables; a line can have one without the other. The next chapter adds destination back in deliberately: Approaching takes this same adjacent motion and aims it, on purpose, at a specific target one step away.
The Microscope
The bass plays the same three ascending steps both times. Only whether the harmony moves to meet them changes.
A — Stepping, no destination. The harmony never changes, so the steps are pure contour.

The identical opening three steps, now landing precisely on the new chord's root.

Listen
Play Harmony only on both: A holds one chord for two bars; B changes chord exactly when the steps would logically continue. Now play Full and compare. The bass gesture in bar 1 is identical in both versions — the difference only becomes audible once bar 2 either repeats the same harmony (A) or arrives somewhere new (B).
See
In A, the steps end where they started (C up to E, back down toward D) — a shape with no destination stated anywhere on the page. In B, the final step lands exactly on the new chord symbol’s root, at the exact moment it appears. The notation itself shows the difference: alignment between a bass arrival and a chord symbol is what turns Stepping into Connecting Chords.
Play

Play all four bars without letting any note announce itself as more important than the others — the point is the shape of the line, not any one arrival. Then notice: the line never had anywhere it had to go, and it was still satisfying to play.
Vary
Keep every pitch and rhythm identical. Add a new chord symbol under bar 4’s final G (say, a C/G or a G7). Does the line retroactively feel like it was heading toward that destination all along, even though nothing about the bass part itself changed?
The Music
“Even Ground” is an original eight-bar jazz study, swung throughout, built almost entirely from stepwise motion, even as the harmony itself moves through a I-vi-ii-V in Eb major, each chord voiced as a full ninth chord.

Reflection
Several notes in “Even Ground” land exactly on a new chord’s root or a close chord tone as the harmony changes — moments that are arguably Connecting Chords, not pure Stepping. Find one and explain what makes it a destination rather than just another step in the contour.
