The chords every piano and keyboard player should know are the basic Major, minor, Augmented, and diminished chords, and seventh chords. These are the most common chords and are relatively easy to play.
These chords are shown with the root note C. Other root notes are possible by transposing these chords. For example, a C Major chord (C, E, G) can be transposed to D. This will result in a D Major chord (D, F-sharp, A).
These chords are constructed from musical intervals. Each chord has:
- A Root note
- A note a Major third (M3) or minor third (m3) above the Root
- A note a Perfect fifth (P5), Augmented fifth (A5), or diminished fifth above the Root
- And seventh chords also have a note a Major seventh (M7), minor seventh (m7), or diminished seventh (d7) above the Root.
- Major - Root, M3, P5
- minor - Root, m3, P5
- Augmented (Aug) - Root, M3, A5
- diminished (dim) - Root, m3, d5
- 7 - Root, M3, P5, m7
- M7 - Root, M3, P5, M7
- m7 - Root, m3, P5, m7
- dim7 - Root, m3, d5, d7
- half dim7 - Root, m3, d5, m7
