3 Bars of Beatle-y Harmonic Magic

There are entire worlds of music theory embedded in just a few bars of Beatles music. One prime example comes from the early hit “All My Loving,” where the progression C#m → C+ → E spans just three measures but opens up a harmonic rabbit hole. It’s a masterclass in voice leading, deceptive resolution, chromaticism, and emotional coloring. This blog post dives into those three bars of Beatle-y harmonic magic and extracts every bit of gold from them.

The Progression in Context

The song is in the key of E major. The progression we’re looking at occurs during the verse:

| C#m | C+ | E |

At first glance, it looks like an odd sequence: a minor chord, followed by an augmented chord, followed by the tonic. But hidden in this three-bar phrase is an exquisite interplay of harmonic and linear motion.

Step 1: Diatonic Function and Immediate Questions

• C#m is the vi chord in E major.
• E is the I chord.

So we start on a minor chord that is diatonically related to the key, and then resolve to the tonic. Easy enough. But what is C+ doing in the middle?

C+ (C augmented) is not diatonic to E major, nor is it an obvious secondary dominant. It contains the notes:

C – E – G#

At this point, we begin to uncover the first layer of magic.

Step 2: Voice Leading and Chromatic Bass

Take a look at the bass line across the three chords:

• C#m: root is C#
• C+: root is C
• E: 5th (which is B) is often in the bass (to make the chord E/B)

That’s a chromatic descent: C# → C → B. That alone is a compelling reason to insert C+ – it enables a beautifully smooth line, pulling the harmony downward toward tonic resolution.

Voice leading in the upper voices is also brilliant:

• E and G# are present in all three chords, providing a strong internal throughline.
• Only one note changes each time: C# becomes C, then resolves to B. This creates both movement and cohesion.

This is the Beatles (and likely George Martin’s influence) demonstrating the classical concept that strong voice leading can make any chord progression work, regardless of its functional identity.

Step 3: Chromatic Passing Chord

One of the most practical and accurate ways to understand the C+ is as a chromatic passing chord. Between C#m and E, C+ creates a bridge:

• C#m: C# – E – G#
• C+: C – E – G#
• E: E – G# – B

From a linear standpoint:

• C# → C → B (bass)
• E and G# stay the same

This kind of motion is commonly found in jazz and classical music. It prioritizes smooth stepwise motion over traditional diatonic function. It’s a subtle but powerful example of harmonic movement driven by voice-leading logic rather than Roman numeral theory.

Step 4: Deceptive Cadence Reimagined

There’s another layer of interpretation: a deceptive cadence.

The chord C+ is enharmonically equivalent to G#+:

• G# – B# – D## (which sounds like C – E – G#)

So, what if we imagine C+ as a disguised V+ of C#m? In traditional theory, G#+ resolves to C#m.

But in this case, the music goes from C#m to C+, not the other way around. Instead of resolving to the tonic of its own key, the supposed dominant (C+) moves away from its expected resolution and lands on E major. That sets up a deceptive expectation — it hints at a resolution to C#m (as if returning), then sidesteps into E major.

This move acts like a reverse deceptive cadence: instead of V → vi, it’s like vi → V+ → I, but with a twist that scrambles the expected dominant-tonic relationship.

The emotional effect is just as important: there’s a moment of tension and ambiguity in the C+ chord. When we land on E, it feels like an unexpected but satisfying resolution, as if the sun comes out from behind a cloud.

Step 5: Implied Chords and Rootless Harmony

Here’s another fascinating lens: C+ as a rootless C#m(maj7).

C#m(maj7) = C# – E – G# – B#

Strip away the root (C#), and you’re left with:

• E – G# – B# (enharmonic to C)

That’s the same thing as C+. So in a very real sense, the chord keeps us psychologically anchored in C# minor, even while pulling us toward E. It’s as if we’re hearing the ghost of C#m(maj7) without the root.

This isn’t just a theoretical parlor trick. This kind of rootless harmony is a staple in jazz and sophisticated pop writing. It allows the emotional coloration of the maj7 to shine through while allowing the bass (and overall harmony) to move freely.

Step 6: Chord Substitution and Expressive Coloring

C+ is also acting as a substitute for something more traditional, like a diminished passing chord or even a secondary dominant. It’s not following standard function, but it achieves something far more expressive:

• It’s smoother than inserting a C#7 (which would be too jarring)
• It’s more colorful than a plain C major (which would clash)
• It’s more emotionally ambiguous than an A or G#7 (which would be too stable)

This puts C+ in the category of what jazz musicians call **”color chords”—chords used for their texture, emotional impact, and linear logic rather than function.

Step 7: The Beatles’ Broader Harmonic Toolkit

This three-chord moment reflects a larger Beatles strategy:

• Using chromaticism and non-diatonic harmony sparingly but effectively
• Creating emotional depth through harmonic surprise
• Prioritizing voice leading over textbook functional progressions

You hear similar techniques in songs like:

• “Michelle” (with its borrowed chords and chromaticism)
• “If I Fell” (with its deceptive resolutions)
• “Something” (with its lush voice-leading and ambiguous dominants)

The Beatles weren’t classically trained in the traditional sense, but they had an uncanny instinct (and the help of George Martin) for how to use harmony to guide the listener’s emotional experience.

Final Takeaways

These three bars from “All My Loving” are a treasure trove of musical insight:

1. Voice Leading Trumps Function: The bass motion (C# → C → B) and the internal consistency of E and G# create cohesion, making even unusual chords feel natural.
2. Augmented Chords Are Gold: C+ adds tension, warmth, and ambiguity. It can act as a dominant, a passing chord, or an upper structure voicing.
3. Multiple Analyses Can Coexist: C+ can be viewed as:
   • A chromatic passing chord
   • An enharmonic dominant
   • A rootless maj7 chord
   • A deceptive gesture
4. Small Choices, Big Results: These three measures last only a few seconds in the song, but they elevate the entire harmonic landscape.

So next time you find yourself stuck with a bland chord progression, remember this passage. Insert a chromatic passing chord. Borrow from another key. Remove the root. Use a substitution. Follow a chromatic line. In just three bars, the Beatles show how these techniques can bring harmonic magic to life.

And that, dear reader, is why we study the Beatles.
