My chord counting system is a quick and easy way to define and play one of the most basic of all piano chords: the Diminished Triad. I show you how in the quick video below.

Three steps:

  1. Hold down any note. this will be the “root” note of the triad.
  2. While holding down the root note, count up 3 half-steps.
  3. While holding down both notes, count up 3 half-steps from the 2nd note.
  4. Play all three notes simultaneously and you have a Diminished Triad (named after the root note, i.e., if the first note you held down is a D note, then the resulting triad is called D Diminished Triad.

Remember this phrase: “Root–3–3,” the counting scheme for creating a minor triad.
