A Triad is a 3 note chord and is essentially the smallest chord. A Major Triad is based on the 1st (Root) - 3rd & 5th notes of a major scale. Inversions change the order of the notes by playing a different note as the lowest note of the chord.
The chord symbols are written using a slash (/) such as C/E which means to play a C major chord with the E note as the lowest note in the chord. These chord symbols are common to other instruments such as keyboards.
There are 3 types of Triad inversions;
| Root Position
|| 1 3 5
|| = C E G
| 1st Inversion
|| 3 5 1
|| = E G C
| 2nd Inversion
|| 5 1 3
|| = G C E
The following chord pattern diagrams are of a block form (or Caged System),
which means you can move the same finger pattern for each Major Triad Inversion
up and down the guitar fretboard.
