A triad is a chord made up of three notes: the root, the 3rd and the 5th. Triads are the building blocks of most chords in music. There are four main types of triads, determined by the intervals between the notes, major, minor, diminished and augmented.

Triads can be used to create smooth transitions between chords in progressions, especially when used in inversions. By using triads across different strings and fretboard positions, you can create different voicings and sounds without always relying on full chord shapes.

Triad formulas
1 3 5 major
1 b3 5 minor
1 3 #5 Aug
1 b3 b5 Dim
1 4 5 Sus4
1 2 5 Sus2

Inversions of triads occur when the notes of the triad are rearranged so that a note other than the root is in the bass. There are three types of inversions. Root Position where the root is the lowest note. First Inversion where the 3rd is the lowest note. Second Inversion where the 5th is the lowest note.
