While many pianists inwardly groan when they hear the word “theory,” chord theory is a vital part of learning to play well-especially for congregational singing!
Spend a little time learning (or brushing up on) some basic chord theory and it will make a big difference in how you play for church.
The terms “triad” and “chord” are often used interchangeably. Technically, a triad is a 3 note chord. There are only seven possible triads, although the notes in each one may come in any order. The very first step to using chords confidently is to memorize the triad vocabulary.
The Triad Vocabulary

As you can see, the triads are built from every other letter in the musical alphabet. The first letter is the ROOT of the triad and it’s where the chord name comes from. An “A” chord will always have the spelling of A-C-E.
When the chord is in root position (stacked up every other note) the A is always on the bottom. When the chord is inverted (C-E-A for example) it is still an “A” chord. Those three notes will always combine to create an “A” triad.
Accidentals (#’s and ♭’s) are added to the basic triad when you are playing in a certain key signature.
For example, when you are playing in the key of D major, the D triad will be spelled D-F#-A. The letter names will always be the same, but sharps and flats will change depending on the key signature.
Personal Practice
- Print out the circle of fifths handout linked below and review all your key signatures (major and minor) so you are familiar enough to identify how many sharps/flats are in any given key.
- Memorize the correct spelling of the triad vocabulary
