FA
Tension Peak
Maximum dissonance. Forms a tritone with TI — the most unstable interval in the key. The strongest ache in the scale.
Subdominant · Rank 7 of 7
6
TI
Leading Urgency
Strong magnetic pull upward to DO. Tritone partner with FA. Together they are the most active tones in the key — the harmonic engine of dominant tension.
Leading Tone · Rank 6 of 7
5
RE
Open Yearning
A question without an answer. Wants to fall back to DO or rise to MI. Forward-moving energy — perfect for verse phrases that keep listeners leaning in.
Supertonic · Rank 5 of 7
4
LA
Warm Border
Moderate tension with emotional warmth. Can linger without full resolution. The soul and gospel note — holds feeling without forcing an answer.
Submediant · Rank 4 of 7
3
MI
Sweet Stability
Warm and settled. The 3rd partial of the overtone series — naturally consonant with DO. Emotionally bright and singable. Rest here feels earned and pleasant.
Mediant · Rank 3 of 7
2
SO
Strong Confidence
The dominant — acoustically the closest partner to DO. Strong, forward-facing, and fully supported. Not home, but near it and confident. Power and resolve without full arrival.
Dominant · Rank 2 of 7

DO
Home Base
The tonic — maximum stability. The key center. Every other note in the key is defined by its relationship to DO. Landing here feels like arriving.

The Tritone Pair
FA
↕
TI
FA + TI = Tritone. The most dissonant interval in the key. FA pulls down to MI; TI pulls up to DO. Together they define the strongest harmonic tension available.
▼Most Stable
Start Here — Home Base
DO is the tonal center — the note every other scale degree is measured against. A melody that returns to DO feels resolved. Verse endings on RE or TI; chorus endings on DO or SO.
Maximum Tension — Use With Intent
FA at the top of the ladder isn't a mistake — it's a power tool. Blues, soul, and gospel use FA constantly for its ache. But FA needs resolution. It cannot be a resting point without creating listener fatigue.
