    A few tricks for zooming around the fingerboard inspired by Billy.

    Lets say you wanted to zip up the neck fast on E7. Play the E, F# and G# on the low E then slide into the A major scale.and run it up the neck.

    How about running Em7 fast up the neck. (Assume E dorian). Play E F# G then run the A7 scale.

    How about G Phrygian? Use C aeolian.

    Whats the trick?

    Think of modes in order by flatting:
    4 lydian
    1 ionion
    5 myxolydian
    2 dorian
    6 aeolian
    3 phrygian
    7 locrian

    This pattern is equivalent to the cycle of 4ths. So a note a 4th away is one mode higher on the cycle..

    E major = A lydian
    E7 = A major
    E dorian = A7
    E aeolian = A dorian,
    E phrygian = A aeolian

    So if you want to play F# dorian, use the B7 scale. Etc.

    I use this a lot moving up and down the neck.

    Going by 4ths can be extended.

    Em7 =A7 =Dmaj7=G lydian. Run this as an Em7 scale in open positionup to the open D, then move up to the 9 position and play a D maj scale continuing with the E at the 12 fret.

    Gm7=C7=Fmaj7=Bb lydian (run this at the 1st,5th and 7th frets).

    So the "trick" is thinking of the same set of notes as multiple scales instead of just one?
    I suppose it's a potentiallly useful shortcut to recalling fingerings if you haven't practiced your scales thoroughly across the neck.

    Fair statement, . The 2 common extra scales are the major and dom7 scales which are pretty fast

    I didn't mean to belittle the idea-
    music theory is basically various ways to look at the same 7 out of 12 notes
    more ways to see it = more information.
    and as Anthony Wellington says "Knowing something is better than NOT knowing something."

    You could also adapt the idea to any mode, just find the right jumping off point
    To zip up the neck really fast on an E7
    play E F# G# on the E string, Open A, Then jump to B Mixolydian on the A string
    play E F# G# on the E string, Open A, B, on the a string , Then jump to C Aeolian
    etc...

    But I have found the fastest way to plot my course across the neck within a given harmony is arpeggios

    I do lots of arpeggios as well.

    I practice a lot of scales but I would have trouble running some up the neck like Ebm7, F#m7 or Bbm7, so I use this trick a lot.

    For example, F#m7 (dorian)= B7=E=A#4 (Lydian)

    And you can arpeggiate that if you don't want to play the scale.
