Chord tones

The notes in C minor

A minor triad reverses the major arrangement: a minor third first, then a major third. Only the middle note moves, yet the chord sounds noticeably darker and more inward. Minor triads sit on the second, third and sixth degrees of a major scale, and on the first degree of a minor key.

Each tone of C minor with its interval, scale degree, distance in semitones from C and a suggested right-hand finger.

Step by step

How to play C minor on piano

  1. Find C: it is the white key immediately left of every group of two black keys.
  2. Build upwards from C using 3 and 7 semitones to reach Eb and G.
  3. With the right hand, place finger 1 on C, finger 3 on Eb and finger 5 on G. Keep the wrist level and the knuckles rounded.
  4. Move your hand a little further in towards the fallboard so the black key sits comfortably under your fingers.
  5. Play the notes together, then one at a time from the bottom up, and listen to how C minor settles.
  6. Try first inversion as well: Eb – G – C. Inversions let you change chords without jumping around the keyboard.

Inversions

C minor in 3 positions

An inversion keeps the same 3 notes and simply moves the lowest one up an octave. Learning them means you can change chords with small hand movements instead of jumping to a new part of the keyboard.

Root position

C – Eb – G

The root C is the lowest note. This is the shape most people learn first.

First inversion

Eb – G – C

Eb is the lowest note, so the minor third sits in the bass and the notes below it move up an octave.

Second inversion

G – C – Eb

G is the lowest note, so the perfect fifth sits in the bass and the notes below it move up an octave.

In context

Which keys contain C minor

In E♭ major the chord functions as vi. Altogether it is produced by the scales of 6 keys, so learning it once pays off in several places.

  • E♭ majorvi
  • A♭ majoriii
  • B♭ majorii
  • C minori
  • F minorv
  • G minoriv

Chord tones are spelled by the degree they occupy, so the third of a minor chord is written as a flat rather than a sharp even though it is the same key on the piano. A double sharp such as F## means the key one whole tone above F.

Compare

C minor against C major

C minor and C major share C and G. Moving the major third E down 1 semitone to the minor third Eb turns C major into C minor.

Practise the pair together: hold the shared notes C, G still and move only the one finger. Hearing that single change is the quickest way to recognise the two chords by ear.
