Why it sounds like that

Raise the fourth of F major to B and the fifth to C♯. The scale differs from F ionian augmented only at the fourth degree. The major seventh is E.

When to use it

Play over F augmented or F augmented major 7th in jazz ballads. The raised fourth adds a dreamy quality to slow harmonic rhythms.

Which position to practise

Learn Box 1 first. The root on string 4, fret 1 keeps the hand low and the range 1–5 avoids open-string position shifts.

Common questions

Which note is the augmented fifth?

The augmented fifth is C♯. It is one semitone higher than the perfect fifth C in F major.

Can I play this over an F major chord?

No. The C♯ clashes with the natural fifth C in F major. Use only augmented or augmented major seventh chords.

Is the open E string usable?

Yes. The open E is the major seventh and a chord tone. It works as a passing note or pedal.
