Jimmy Webb wrote “Wichita Lineman” in 1968 and sent it to producer Al De Lory with a warning: the third verse and bridge weren’t finished yet. Glen Campbell recorded it anyway, turning the gap into an instrumental passage — and that incompleteness became part of what makes the song so haunting. In this lesson, Marty Schwartz breaks down the full chord progression, the jazzy voicings that make the song sound so unusual, and how to handle the chromatic bassline in the chorus.
What Makes This Song Different
Most of the chord names you’ll find on tabs and sheet music for this song are piano-and-orchestra voicings — they get complicated fast. Marty cuts through all of that and teaches it the way it actually works on guitar, especially if you’re playing solo without a bass player underneath you. The song is in the key of F, and it leans heavily on barre chords and slash chords (chords with a specific bass note). It’s not hard, but it does ask your fretting hand to stay active throughout.
The Intro: F Major 7 Over C and B♭ Over C
Marty starts at the eighth fret for the intro. The first chord is F major 7 over C — a barre chord shape with the eighth fret on the low E string providing the C bass note. Here’s the full fingering: 8 on the low E, 8 on the A, 10 on the D, 9 on the G, 10 on the B, barred. The A string and high E are muted — the A string mutes naturally from the third finger, and the palm takes care of the high E.
The second chord is B♭ over C. Marty keeps the eighth fret on the low E with his third finger and pinky, moves to the eighth fret on the D string, seventh fret on the G with the middle finger, and sixth fret on the B with the index. It sounds jazzy because of that C pedaling underneath two different chords. The whole intro pattern happens twice.
The Verse Chords
Four chords carry the verse. Marty walks through each one:
B♭ major 7 (E-root voicing) — index finger on the sixth fret of the low E string, middle finger on the sixth fret of the B string, third finger on the seventh fret of the D, pinky on the seventh fret of the G. The A string gets muted by the index finger, the high E by the palm.
A minor 7 — middle finger on the fifth fret of the low E, third finger barring the fifth fret across the D, G, and B strings. The A string mutes naturally from the middle finger. Marty notes that this chord functions like a type of C chord — the A is in the bass, which is what gives it that suspended quality.
G minor 7 over C — the easiest chord in the song. Marty just barres across the third fret starting from the A string. One finger, that’s it. He sometimes calls this B♭ over C — the two names are essentially interchangeable here, and he chose this voicing because of how it sets up the hand for the next move.
After those three chords, the verse splits into D minor for two counts, A minor for two counts, and then G major for four counts. That G major finally gives the fretting hand a break from barring — Marty plays it with the open B string in there, which matches the vocal melody.
The Chorus: A Chromatic Bassline in Disguise
This is where tabs overcomplicate things. Some charts call the first chord of the chorus “A7sus4 with a C in the bass.” Marty says it plainly: it’s a C major chord. Two full bars of it — eight counts. The fancy naming comes from what the orchestra is doing around it, but the guitar part is just C major.
What follows is a chromatic descent in the bass — C to B to B♭ — which is actually why the chorus sounds so dramatic and moving. Here’s the sequence:
- C major — two bars (eight counts)
- G over B — standard G chord shape with the second fret A string as the lowest note, one bar
- B♭ major — first fret A-root barre chord with A major shape, third fret on D, G, and B, one bar. If you’re playing without a bass player, Marty recommends following this with D major rather than letting the open A ring.
- D major — one bar
- A sus 4 — open A string, A major chord shape, plus pinky on the third fret of the B string, one bar
Then the verse chords return: B♭ major 7, and then a C add 9 (third fret A, open G, third fret B, third fret high E). That pattern does the whole cycle twice before landing on B♭ over C to close it out — and then the whole song starts over.
Two Voicings of B♭ Major 7
Marty is deliberate about this: he plays B♭ major 7 two different ways in the song, and the reason matters. In the verse, he uses the sixth-fret E-root voicing because it flows directly into A minor 7 and G minor 7 over C — those three chords together behave like a C11 or C suspended chord, and the hand position makes that movement easy. Later in the song he switches to the first-fret A-root voicing (first fret A, third fret D, second fret G, third fret B). Same chord name, different feel, different hand position.
One Chord Per Bar — With One Exception
Everything in this song gets at least four counts. The one exception is D minor to A minor in the verse — those two split a single bar, two counts each. Everything else sits for a full bar or longer. The C major in the chorus and the D major at the end of the chorus each get two full bars. Marty makes this clear in the playthrough, and it’s worth locking in before you try to play along — rushing those single-bar chords is the most common place people lose the feel of the song.
Putting It Together
This song rewards patience. The barre chords stack up quickly — F major 7 over C, B♭ major 7, A minor 7, G minor 7 over C, B♭ major — and the fretting hand doesn’t get many breaks. Use the D minor, A minor, G major section in the verse to shake it out when you need to.
What makes the song worth the work is exactly what made it a classic. Carol Kaye’s descending bass intro, Webb’s chromatic voice-leading in the chorus, Campbell’s eerie slack-key fade — they all point to the same thing. It’s a simple story told with unusual sophistication. Bob Dylan reportedly called it “the greatest song ever written.” Once you hear the chord movement under the chorus, it’s hard to argue.
Marty’s breakdown makes the harmony approachable. The chords have fancy names on paper, but under the fingers they’re mostly barre shapes that follow a logical path. Work through each section slowly, get the hand positions solid, and then run the full progression from top to bottom.
