Borrowed_chord

A borrowed chord is a chord borrowed from the parallel key. If the root of the borrowed chord is not in the original key, then they are named by the accidental. For instance, in major, a chord borrowed from the parallel minor\'s sixth degree is a "flat six chord" written $\backslash flat$VI. Borrowed chords are an example of mode mixture.

Six chords borrowed from the parallel minor key are commonly found in the Baroque, Classical and Romantic eras (shown here in C major):

• Diminished Supertonic Triad (ii°): D, F, A flat
• Half-Diminished Supertonic Seventh (ii^Ø7): D, F, A flat, C
• Major Triad on the Lowered Third Scale Degree, or "Flat Three" ($\backslash flat$III): E flat, G, B flat
• Minor Subdominant (iv): F, A flat, C
• Major Triad on the Lowered Sixth Scale Degree, or "Flat Six" ($\backslash flat$VI): A flat, C, E flat
• Fully Diminished Leading-Tone Seventh (vii°⁷): B, D, F, A flat

The following three chords are also found in Romantic era, albeit rarely:

• Minor Subdominant Seventh (iv^{$\backslash flat$7}): F, A flat, C, E flat
• Major-Minor Subdominant Seventh (IV^{$\backslash flat$7}): F, A, C, E flat
• Dominant Flat Ninth (V^{$\backslash flat$9}): G, B, D, F, A flat

The Major-Minor Subdominant Seventh, which contains an A natural, is borrowed from the parallel ascending melodic minor scale.

In popular music, the Major Triad on the Lowered Third Scale Degree ($\backslash flat$III), the Major Triad on the Lowered Sixth Scale Degree($\backslash flat$VI) and the Major Triad on the lowered Seventh Scale Degree, or "Flat Seven" ($\backslash flat$VII, in C major: B flat, D, F) are common.

Borrowing from a parallel major key is a common feature of grunge music,and can be occasionally be found in other styles of post-grunge Rock.Otherwise it is generally limited in western music to ending a minor piece on a major tonic triad, a chord which is then called a Picardy third, and use of the Major Dominant chord (in C minor: G, B, D). However, the latter of these could also be viewed as use of the Harmonic Minor scale.
