Below is a side-by-side, written-notation comparison that shows how the harmony is actually constructed in classic Barbershop versus advanced jazz-vocal writing as used by The Four Freshmen and later The Hi-Lo’s.

To keep this concrete and readable, I’ll use concert C major, one bar per harmony, SATB-style layout, and explain what’s happening musically under each example.

==== 1️⃣ Barbershop Harmony (Vertical, chord-locked) ====

Defining traits
* Every syllable = one complete chord
* Chords stack tightly (close position)
* Strong emphasis on dominant 7ths, ringing overtones
* Voices move together rhythmically
* Melody often sits inside the chord (not always on top)

===== Example: C → G7 → C (classic barbershop cadence) =====

<syntaxhighlight>Treble Clef
Tenor:     G4  | F4  | G4
Lead:      E4  | D4  | E4
Baritone:  C4  | B3  | C4
Bass:      C3  | G2  | C3
             C     G7     C

</syntaxhighlight>

What’s happening
* Every beat spells a complete chord
* The G7 is tuned purely (7th often lowered slightly for ring)
* Motion is blocky and vertical
* No extensions beyond 7ths
* No independent counter-melody

🎯 Goal: harmonic “lock and ring,” not linear interest

==== 2️⃣ Four Freshmen Harmony (Linear, jazz-driven) ====

Defining traits
* Melody on top, harmony supports it
* Extensions (9, 11, 13) are normal
* Inner voices move independently
* Frequent drop-2, open voicings
* Chords implied over time, not always fully spelled

===== Example: Cmaj9 → A7♭9 → Dm9 → G13 =====

<syntaxhighlight>Treble Clef
Tenor:     D5   | C#5 | E5  | F5
Lead:      G4   | G4  | F4  | E4
Baritone:  E4   | C#4 | D4  | B3
Bass:      C3   | A2  | D3  | G2
           Cmaj9  A7♭9  Dm9   G13

</syntaxhighlight>

What’s happening
* Melody (Lead) is lyrical and horizontal
* Harmony unfolds through voice-leading
* Bass defines roots; upper voices define color
* Chords often lack the root or fifth
* Jazz function > overtone lock

🎯 Goal: smooth swing, harmonic sophistication

==== 3️⃣ Hi-Lo’s Harmony (Maximum sophistication) ====

The Hi-Lo’s pushed this even further.

Defining traits
* Counter-melodies everywhere
* Rootless voicings common
* Frequent chromatic inner-voice motion
* Voicings often derived from big-band sax sections
* Harmony may contradict the melody rhythmically

===== Example: G13♭9 → Cmaj9♯11 → F13 → B7♭9 =====

<syntaxhighlight>Treble Clef
Tenor:     F5  | F#5 | A5  | A#5
Lead:      B4  | E5  | G4  | F#4
Baritone:  E4  | D4  | D4  | D4
Bass:      G2  | C3  | F2  | B2
          G13♭9 Cmaj9♯11 F13 B7♭9

</syntaxhighlight>

What’s happening
* Each voice has its own logic
* Chords are implied, not stacked
* Extensions define identity
* No concern for “ringing” overtones
* Harmony is closer to Gil Evans than barbershop

🎯 Goal: modern jazz color and motion

==== 🔍 Summary Table ====

| Feature       | Barbershop           | Four Freshmen     | Hi-Lo’s                |
| ------------- | -------------------- | ----------------- | ---------------------- |
| Harmony style | Vertical             | Linear            | Contrapuntal           |
| Chord types   | Triads, 7ths         | 9ths, 13ths       | Altered, ♯11           |
| Voice motion  | Together             | Independent       | Highly independent     |
| Tuning goal   | Overtone ring        | Equal temperament | Expressive tension     |
| Influence     | Hymns, Tin Pan Alley | Jazz combos       | Big band / modern jazz |

==== 🎷 Why this matters (musically) ====

Barbershop is chord-centric
Four Freshmen are melody-centric
Hi-Lo’s are texture-centric

Same four voices — completely different musical brains.

If you want, I can:
* Rewrite a barbershop tag in Four Freshmen style
* Show a Barry Harris lens on Freshmen voicings
* Convert a jazz lead sheet into each style side-by-side

Just tell me which direction you want to go.
