How to use the Powell Fretboard System

The following is an overview of how to use the Powell Fretboard System. Feel free to click away on the choices - you really can't do anything wrong - but you sure can learn a lot. The main purpose for me, and why I created this, was to see the relationships of scales, playing positions and triads in various inversions. Have fun!

Key Selection

This section allows you to draw a scale for any key across the entire fretboard. Simply click a key and the system draws the scale and highlights the root.

Clicking on another key will change the key. Clicking on the active key will clear the fretboard

Major/Minor

When a key is active, you have the option of choosing Major or Minor scale.

Diatonic/Pentatonic

When a key is active, you have the option of choosing Diatonic (seven note scale) or Pentatonic (five note scale).

Playing Positions

This section allows you to highlight a region of the fretboard to quickly locate playing positions. If Diatonic is chosen in the Key Selection area, then you have seven playing positions, one for starting on each note of the diatonic scale. If Pentatonic is chosen in the Key Selection area, then you have five playing positions, one for starting on each note of the pentatonic scale. This section is only enabled if you select a key.

CAGED Highlighting

This section allows you to highlight the C-A-G-E-D chord shapes based on the active Key Selection. This section is only enabled if you select a key.

Chord Triad Selection

This section allows you to highlight a closed triad (one of four types of triads) in one of four string set positions and in one of four inversions

Key

When a key is active, you have the option of choosing the type, inversion, and string position of the triad.

Triad Type

If a triad key is active, you can select one of four types of triads: Major, Minor, Diminished, or Augmented.

Inversion

If a triad key is active, you can select one of three types of inversions: Root (1-3-5), 1st-Inversion (3-5-1), and 2nd-Inversion (5-1-3)

String Group

If a triad key is active, you can select one of four types of string grouping: Strings 6 through 4, 5 through 3, 4 through 2, and 3 through 1 respectively.
