Knowing how to read and write chord names is an easy yet invaluable skill. Chords are often
written in a kind of shorthand that makes them instantly recognizable (and gives you the free-
dom to play them with the voicing or inversion that you prefer). Once you understand the
basic principles of harmony and chords, it’s very simple to use this shorthand to write out the
chords of a song.
First, write the root note of the chord in an uppercase letter. If you need to specify sharp or flat,
indicate that to the right of the root. The chord type should be indicated to the right as well.
Examples for the key of C are shown below.
One important point: Chords are made up of notes “stacked” on top of each other, and the
stacked notes are indicated in the chord name of the chord type as a number — the number
being the distance of the note from the root. (See the keyboard diagram below.) For example,
the minor 6th chord includes the 6th note of the scale, the major 7th chord has the 7th note of
the scale, etc.
The Intervals of the Scale

used to represent them in the chord name, study
