A borrowed chord (viio4
3
= B–D–F–A) in J.S. Bach's Prelude No. 1 in C Major from The Well-Tempered Clavier

A borrowed chord (also called mode mixture,[1] modal mixture,[2] substituted chord,[3] modal interchange[1], or mutation[4]) is a chord borrowed from the parallel key (minor or major scale with the same tonic). Borrowed chords are typically used as "color chords", providing harmonic variety through contrasting scale forms, which are major scales and the three forms of minor scales.[2] Chords may also be borrowed from other parallel modes besides the major and minor mode, for example D Dorian with D major.[1] The mixing of the major and minor modes developed in the Baroque period.[5]

Borrowed chords are distinguished from modulation by being brief enough that the tonic is not lost or displaced, and may be considered brief or transitory modulations[3] and may be distinguished from secondary chords[6] as well as altered chords.[1] According to Sheila Romeo, "[t]he borrowed chord suggests the sound of its own mode without actually switching to that mode."[1]

A borrowed chord (viio4
3
= G–B–D–F) in Mozart's Piano Sonata No. 18, mvmt. II[7]

Sheila Romeo explains that "[i]n theory, any chord from any mode of the scale of the piece is a potential modal interchange or borrowed chord. Some are used more frequently than others, while some almost never occur."[1]

In the minor mode, a common borrowed chord from the parallel major key is the Picardy third.

In the major mode, the most common examples of borrowed chords are those involving the scale degree 6, the lowered sixth scale degree. These chords are shown below, in the key of C major.[8]

  • viio7: B–D–F–A
  • iio: D–F–A
  • iiø7: D–F–A–C
  • iv: F–A–C
 {
\override Score.TimeSignature #'stencil = ##f

  \clef treble 
  \time 4/4
  <b d f aes>1_\markup { \translate #'(-7.5 . 0) { \concat { \small "C Maj.:" \hspace #1 \normalsize "vii" \raise #1 \small "o7" \hspace #3.5 "ii" \raise #1 \small "o" \hspace #5.5 "ii" \raise #1 \small "ø7" \hspace #5 "iv" } } }
  <d f aes> <d f aes c> <f aes c> \bar "||"
} }

The next most common involve the scale degree 3 and scale degree 7. These chords are shown below.[9]

  • i: C–E–G
  • VI: A–C–E
  • iv7: F–A–C–E
  • III: E–G–B
  • VII: B–D–F

A backdoor progression in C. VII7 is borrowed from the parallel minor rather than Mixolydian as VII may be.

Chord progressions may be constructed with borrowed chords, including two progressions common in rock music, I–VII–VI–VII, common everywhere, and I–VI–IV (About this soundPlay ), used by bands like Genesis, Yes, and Nirvana.[1] VII is from Mixolydian and VI is found in both Aeolian and Phrygian.[1] The VII–I cadence with VII substituting for V is common, as well as II–I, III–I, and VI–I.[10] In popular music, the major triad on the lowered third scale degree (III), the major triad on the lowered sixth scale degree (VI) and the major triad on the lowered seventh scale degree, or "flat seven" (VII) are common.

Borrowed chords have typical inversions or common positions, for example iio6 and iiø6
5
, and progress in the same manner as the diatonic chords they replace except for VI, which progresses to V(7).[2]
