What makes Faug different

One key changes and the chord changes family.

Chord	Notes	Third	Fifth
F	F A C	major 3rd	perfect 5th
Fm	F Ab C	minor 3rd	perfect 5th
Fdim	F Ab Cb	minor 3rd	diminished 5th
Faug	F A C#	major 3rd	augmented 5th

Where Faug goes

Faug is the III+ chord in the harmonic minor scale of D minor.
Its thirds are equal, so Faug, Aaug and C#aug use the same three keys: the root is whichever note you treat as home.
A common move is F → Faug → Bb: the raised fifth C# pushes up to D.

Common questions

How do you play Faug on the piano?

Press F, A, C# together: right hand 1-3-5 with the thumb on F, left hand 5-3-1 with the little finger on F.

What is the difference between Faug and F?

One note. F has C on top; Faug moves it to C#. The new fifth is what gives Faug its floating, unresolved sound.

Where does Faug go?

Faug is the III+ chord in the harmonic minor scale of D minor. Its thirds are equal, so Faug, Aaug and C#aug use the same three keys: the root is whichever note you treat as home.

Can I practise Faug with a MIDI keyboard or microphone?

Yes. ChordRunner detects a USB MIDI keyboard automatically and also hears an acoustic piano through the microphone. Faug counts in any position, as long as F, A, C# sound together.
