Fm – Fa Minor
In music theory, F minor chord is built on F-Ab-C formation: root-minor third-major third. Basic minor chord has a formation F-C-F-Ab-C-F from basses to trebles in the guitar.
This chord is derived from a minor triad. In music theory triads are built by three different notes: root-minor third-major third. But in the guitar, generally basic minor chords are expanded by same kind notes that repeat themselves in different octaves. Minor triads may have a function as a supertonic(subdominant parallel), mediant(dominant parallel) or submediant(tonic parallel) besides tonic degree.
