To form a triad, write out its root note on the staff and draw notes a generic third and fifth above it (i.e. draw a snowperson). Next add key signature or any necessary accidentals as needed to indicate its position; additionally triads may feature notes rearranged or doubled over themselves known as inversion.


Intervals form the cornerstone of guitar music – scales, chords and arpeggios alike. While musical alphabet uses letters to represent notes, intervals use numbers instead, which creates learnable shapes on the fretboard.

Intervals may be altered by moving them up or down the fretboard relative to their root note. For example, moving up one fret transforms a perfect fifth interval into a major second; similarly bringing minor seventh interval up one fret gives us diminished seventh.

Understanding intervals is absolutely key to musical development; even altering a chord by just one note can have profound effects on its sound and feel, creating harmony through harmonious chords essential to musical growth.
