Fretboard Evolution Vol. I - Steve Rieck

Minor 7 th (C to Bb) Major 7 th (C to B) Perfect Octave (C to C)
After all of that feels comfortable, remember to study the fretboard slowly
and find and listen carefully to the other interval shapes not shown above.
So to summerize, remember these important points:
• An interval is first and formost measured by the number of actual
letters contained within the interval itself (ie: Just count the
letters).
• The sum of any interval (within an octave) plus it’s inversion will
always equal 9.
• An interval is MAJOR if the top note is in the major scale of the
bottom note and this is NOT TRUE of it’s inversion.
• An interval is PERFECT if the top note is in the major scale of the
bottom note and this is ALSO TRUE of it’s inversion.
• Any major interval that is lowered a half-step and spelled with the
same letters becomes a MINOR interval.
• A major or perfect interval that is raised a half-step and spelled with
the same letters becomes an AUGMENTED interval.
