First of all, what are chords?
Chords are simple at their core. They are a musical element in which multiple notes are played at the same time. It’s common for chords to be the element that set the emotional tone of the song and help create the story in the music. Because chords are made up of notes in a key, chords used in a song are usually in the same key.
Triads
Triads are the most common types of chords that you’ll hear in music today. They’re built by taking the root note and adding the third and fifths of that note.
Let’s use the C Major scale and build a triad.
The C Major triad uses C, E, and G:
- C: Root note
- E: This is the third note up from C in the C Major scale, most often called ‘the third.’
- G: This is the fifth note up from C in the C Major scale, most often called ‘the fifth.’
Move the root note to any other note in the C Major scale, add the third and fifth and you’ve created another chord in the C Major scale. It’s good to be careful of your wording here. Say we moved the root to G. We’d have a G major chord in the key of C.
For example, let’s chose another note from the C Major scale, F. To make a chord from this we will need to add the third, which is A, and the fifth, which is C.
Each scale should be able to make 6 triads. There are also diminished chords at the end of each scale however we won’t bore you with the details of these just yet.
Major/ Minor
We touched on what makes a major and minor scale in the last piece however what is it that makes a major and minor chord? It’s not too hard to get your head around. It’s simply the placement of the third and fifth.
Let’s use C Major and Minor as our example:
A C Major chord is created by playing notes I, III, and V from the C Major scale at the same time. These notes are C (I), E(III) and G(V).
