If the scale or chord that you want to have mapped does not exist in the collection of pre-defined scales and chords, you can submit your own intervals to the user-defined category by following these steps.

• If you haven't already done so, register with GAFF on the register page.
• Back on the submit-intervals, select the intervals that you want included in your scale or chord by clicking on the appropriate checkboxes.
• For each interval that you selected choose one of the available names for the interval. The name that you choose does not affect the mapping of the fretboard figure, but the interval key (which is used to identify the various intervals) will use the interval name. For example, if you were defining the major scale the second interval would be known as "2" (the second). However, if you were defining an Add9 chord, you would name the same interval "9" (the ninth).
• Provide a title-string description. This string will be used as a title on the fretboard figures. By convention, this string should end with "Scale" if the intervals represent a scale or "Chord" if the intervals represent a chord.

The submit intervals page is initialized to values that would define the major scale. Please change these...
