Start with three notes. Find them on the fretboard, change the note in the bass, and listen to the possibilities. These nine study pages are yours to work through at your own pace.

Triads
A chord is a group of at least three notes. Two notes form a dyad, which may be considered a fragment of a chord.
As our basic triad we will use C major. It is built from the C major scale by taking the root, major third, and fifth — moving through the scale in thirds.

the basic C triad
Start with these three notes.
C = C · E · G
C major · D/G/B string set
Rroot3third5fifth
Remove the third
The chord is no longer major or minor: its quality becomes open or suspended. The third is the tone that most clearly identifies major versus minor.
chord symbols and added tones
A simple symbol assumes root, third, and fifth. Every added or altered tone must be named in the symbol.

Inversions
Inversions are different ways of ordering the notes of a chord. They create new sonorities inside the same harmony.
A triad has two inversions in addition to root position. The lowest note changes; the three pitch classes remain C, E, and G.
