Scale Interval Patterns
A scale interval pattern shows you how many semitones (frets on the guitar) are between each note of a scale. In the table below, S stands for semitone (1 fret), T stands for tone (2 frets), and T+S stands for tone plus semitone (3 frets on the guitar). In the diagram below the notes of the C Major scale are highlighted in red, showing the intervals between each of the notes.
