Descending Bass Lines
The lament, the line cliché, and the Pachelbel descent · i – i(maj7) – i7 – i6 · i – ♭VII – ♭VI – V
A descending bass line is one of the most emotionally powerful devices in music. When the bass walks downward — especially the minor "line cliché" (i – i(maj7) – i7 – i6) or the Baroque lament bass (i – ♭VII – ♭VI – V) — it produces a feeling of gravity, sadness, and inevitability that has moved listeners for four centuries. The descending tetrachord was literally the standard way Baroque composers signaled grief, and the same falling line still carries that weight in everything from "Stairway to Heaven" to "A Whiter Shade of Pale".
The minor line cliché — a chromatic inner descent
A held minor tonic with a voice creeping down chromatically inside it: i, i(maj7), i7, i6. The sound of spy themes and torch songs. Try it in any key and hear the line fall.

About Descending Bass Lines
The descending bass line works on the listener through the same association that lifts the ascending one — but in reverse. Falling pitch reads as falling energy, settling, and release of tension toward gravity. When that descent is slow and stepwise, it acquires a quality of inevitability, as if the music is sinking under its own weight. Baroque composers codified this: the descending tetrachord (a four-note stepwise fall from the tonic to the dominant) became the standard "lament bass," used in operatic laments and passions to signal grief. The ground bass of Purcell's "Dido's Lament" is the most famous example.
The minor line cliché is the most beloved descending device in popular music. Over a sustained minor tonic chord, one inner voice creeps downward by half-steps: from the root's octave down through the major seventh, the flat seventh, and the sixth. The chords that result are written i – i(maj7) – i7 – i6, but the harmony barely changes — it is the falling chromatic line you hear, like a single thread of melancholy unspooling inside a held chord. "My Funny Valentine," the James Bond theme, "Michelle," "Stairway to Heaven," and countless film cues use it. The descending line creates exquisite tension while the tonic stays put underneath.
The lament bass proper — i – ♭VII – ♭VI – V — moves the whole bass down by step rather than hiding the line in an inner voice. This is the same descent as the flamenco Andalusian cadence, and it carries the same dark, dramatic weight. In minor it walks from the tonic down through the flat seventh and flat sixth to a dominant. Procol Harum's "A Whiter Shade of Pale" is built on a descending bass derived from Bach; Ray Charles's "Hit the Road Jack" loops a descending minor line; Led Zeppelin's "Stairway to Heaven" opens with a falling chromatic bass. The descent gives all of them their sense of solemn grandeur.
The most ubiquitous descending bass of all is Pachelbel's. The eight-chord loop of his Canon in D (I – V – vi – iii – IV – I – IV – V) has a steadily descending bass under repeated upper voices, and that contour is intrinsically satisfying — which is why it has been borrowed for hundreds of pop songs, from "Basket Case" to "Graduation (Friends Forever)" to "Cryin'." Unlike the minor laments, Pachelbel's descent is in major and reads as gentle and bittersweet rather than grief-stricken, but it works through the same principle: a falling bass under sustained harmony is one of music's most reliable sources of emotional pull.
Variations
