How to use the virtual fretboard: Select a root note from drop-down menu 1. Next select a scale from drop-down 2, or a chord type from drop-down 3. When selecting either a scale or chord you can also display intervals (a color-coded display of the intervals included in either the chord or scale selected). Lastly, when selecting a chord, you can also select different chord voicings, using the ‘voicings’ buttons. If at any time you wish to return to the default fretboard with all notes showing, simply select ‘none’ from drop-down menu 1.
