What a chord is — what happens when you stack notes

A chord is stacked notes. Build one up from one note to three and hear where it starts having a name.

Chapter 6All chapters

Part one covered note names and scales. Now those notes get played at the same time. A chord is not a symbol to memorise; it is the name given to a stack of notes.

A melody plays notes one after another. A chord plays them together — the sound of strumming a guitar. Which notes you sound together changes the character, and every useful combination has a name.

Stack one note, then two, then three

Play C on its own, then add E, then add G. Press them in order. Each addition makes it sound more like a chord and less like a note.

  • CC alone (one note)
  • CC and E (two notes)
  • CC, E and G (a triad)
Notes being added on top of the same C. At three notes it becomes what everyone calls "a C chord".Buttons and keys in the diagrams play sound. Check your volume first.
In plain wordsChord

Two or more notes sounded together. Usually it means three or more, and each combination has its own name.

A triad is "three notes, skipping one each time"

Look at C, E and G inside the scale: it is Do, skip Re, Mi, skip Fa, Sol. Pick three notes skipping every other one — that is how a triad is built. Do the same starting from F or from G and you get the F chord and the G chord.

  • CC (C, E, G)
  • FF (F, A, C)
  • GG (G, B, D)
The skip-one rule is the same wherever you start from.Buttons and keys in the diagrams play sound. Check your volume first.
  • C → F → G → C

    C | F | G | C

Line up the three chords you just built and you already have the skeleton of a song.Buttons and keys in the diagrams play sound. Check your volume first.

Write a melody over just these three chords. The simpler the foundation, the more clearly you hear what the melody is doing.

The one thing to remember

Chords are building blocks. Three notes stacked with one skipped between each is a triad, and triads are the foundation of nearly everything.
