Basic Piano Chords

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:

1. A Root note
2. A note a Major third (M3) or minor third (m3) above the Root
3. 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.

The basic chords:

• Major - Root, M3, P5
• minor - Root, m3, P5
• Augmented (Aug) - Root, M3, A5
• diminished (dim) - Root, m3, d5

The seventh chords:

• 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

Example:

If we choose a Major chord for example we begin by picking a Root note. We could pick any of the 12 notes but in this case we will choose G. The next note we need is a Major third (M3) above the Root, which in this case would be the note B. The final note we need is a Perfect fifth above the root, which in this case would be the note D. Now we have all three notes of our Major chord: G, B, and D.

For reference here is a diagram of the keyboard with the note names on it:

Now that you know these chords you might want to learn about chord inversion, chord symbols, or extended chords.

The Keyboard

The Keyboard is arranged so that the pitch goes left to right, low to high. The keys on keyboard instruments are arranged in a reoccurring pattern. The black keys are arranged in groups of two and three between the white keys.

This pattern continues up and down the keyboard.

The note names of the white keys are:

This key pattern repeats on the keyboard so that the note names of the white keys keep repeating: CDEFGAB-CDEFGAB-CDEFGAB and so on.

Sharps and Flats:

If we take a white key, D for example, and we go up (to the right) to the adjacent black key we are now on the note D-sharp. If we go down (to the left) to the adjacent black key from D we end up on the note D-flat. This is how we determine the names of the black keys and therefore all black keys will be a sharp or flat note.

You may have noticed that black keys can have more than one note name. For example C-sharp and D-flat are on the same black key, but which name we should use depends upon context, such as the Key Signature.

Half-steps and Whole-steps:

A Half-step is the distance of two adjacent notes, such as D to D-sharp, E to F, or A-flat to G. (A half-step is also known as a minor second.)

A Whole-step is the distance of two Half-steps, such as C to D, E to F-sharp, or B-flat to A-flat. (A whole-step is also known as a Major second.)
