How the tension moves

1

Phase 1 • Diatonic Tonic

The Home (Tonic — Degree i)

Fm

Tonal rest function (Riemann, 1893): Acts as the acoustic gravitational center and tonal anchor. All notes of the diatonic scale find stability in this chord. Playing Fm establishes the consonant foundation of the key — generating neither tension nor urgency of movement.

Listen

  1. Fm
It sounds calm, like a starting point that doesn't ask to go anywhere.

Phase 2 • Subdominant and Relative

The Landscape (Relative Major and Subdominant — Degrees VI and iv)

Db

Diatonic voice leading (Schoenberg, 1911): Moving to Db brings the first bright colour into the minor key. Db is the major chord on the sixth degree and shares two notes with Fm, so the change stays smooth before the progression heads toward the dominant.

Listen

  1. Fm
  2. Db
From Fm to Db the color changes, but it remains calm because they share notes.

Phase 3 • Dominant with Tritone

The Adventure (Dominant — Degree V7)

Bbm → C7

Instability and harmonic pull (Rameau, 1722): The dominant chord C7 harbors the leading tone and the diatonic tritone interval. This internal dissonance produces the peak acoustic tension of the progression, and the ear waits for the return home.

Listen

  1. Bbm
  2. C7
It stops on C7 on purpose. Notice how it hangs in the air, asking to come back.

Phase 4 • Authentic Cadence

The Return (Cadential Resolution)

Fm

Release and resolution of tension: The descending fifth bass movement (C7 to Fm) instantly dissolves all accumulated harmonic tension. The tritone resolves contrary-motion into the third and root of Fm, completing the cycle with total acoustic balance.

Listen

  1. C7
  2. Fm
Now, C7 returns to Fm and the tension is suddenly released.

Check it with your ear

Two short questions to solidify what you've just read. There's no grade or record, so if you get it wrong, you can listen again and try again.

Which chord creates the tension that asks to return to Fm?

Listen to both endings. Which one sounds finished?

Try it on your guitar

Play and stay there for four beats without moving. Then play . That relief you feel is the resolution this lesson talks about. Repeat it three times and then try the whole circle at 85 BPM.

Inside the key of F minor

F minor is built from F, G, Ab, Bb, C, Db and Eb. It has four flats, Ab, Bb, Db and Eb.

Ab major uses the same seven notes, which makes it the relative major. Compared with Bb minor, only one note changes, G becomes Gb. Compared with C minor, only one note changes, Db becomes D.

In C7, the third E and the seventh Bb sit six semitones apart, a tritone. In the guitar shape of C7, E sounds on string 4, fret 2 and open string 1 and Bb on string 3, fret 3.

With a capo it also works with other shapes. You can play it with the Em shape and the capo at fret 1 or with the Dm shape and the capo at fret 3.

Theoretical Foundations

All sources

Hear and practise this circle in context

The bass line and the tonal centre

Play Fm alone, then play the four chords in order: Fm – Db – Bbm – C7.

Tonic, preparation and dominant

Apply that map to Fm – Db – Bbm – C7 rather than assuming that the same chord must play the same role in every song. Name the starting chord Fm aloud; then pause after Db and ask which note you still hear as home. Repeat after Bbm and after C7.

When the dominant contains a tritone

In this circle, C7 is a dominant seventh chord: the “7” in its symbol marks the added seventh. Its third and seventh form a tritone, an interval of three whole tones that creates tension toward Fm. Play C7 → Fm below and follow those two inner voices: the third rises by a semitone toward the tonic, while the seventh descends by step to a note in the tonic chord.

Listen

  1. C7
  2. Fm
Now, C7 returns to Fm and the tension is suddenly released.

Common tones and economical fingering

Move from Fm to Db slowly and listen for a pitch that can remain still; if there is none, listen for voices that move by the smallest intervals. Repeat with Db to Bbm, Bbm to C7, and the return to Fm.

A measured practice routine

First play Fm – Db – Bbm – C7 with one downstroke at the beginning of each measure.

Transpose without changing the functions

Compare the two versions by singing the first note of Fm and then the first note of its counterpart in the new key.
