Thread: "Fretboard Logic" for the Mandolin

    Default "Fretboard Logic" for the Mandolin

    I was looking at my old Fretboard Logic guitar book tonight, and thinking about the whole CAGED approach, and how you would apply a similar concept to the mandolin.

    We have an open G that can be played GDB starting from the fourth string.
    Move it down one string and we have open D with DAF# starting from the third string.

    We have open A played C#EA starting from the fourth string.
    Move it down one string and it is E played EC#A

    We have C that can be played GEC starting from the fourth string.
    Move it down one string and it is G played DCG

    Finally, we have D# that can be played GD#A# starting from the fourth string.
    Move it down one string and it is F played DA#F

    All of these chords can be moved up the neck by shifting your fingers and using your first finger to play the open note. (A stretch, though, on that second pair of voicings)

    So, is that it? Are these eight chords (or four pairs of voicings) the mandolin equivalent of the CAGED chords on guitar? Does it work the same way with mandolin scales and the CAGED guitar scales? Is there a better way to organize one's thinking about mandolin chords?

    Oddly, I haven't seen it explained quite this way, and I am a mandolin book addict.

    We tend to talk about inversions, rather than shapes. I guess I am a visual thinker, because it is easier for me to remember shapes.

    Am I missing something glaringly obvious?

    I think I see what you are driving at. I’m fairly visually oriented myself.

    However, I think the CAGED concept is more suited for guitar since the principle is that you move up the neck from chord form to chord form. (i.e. C to A, A to G, etc.).

    As a guitar is tuned in 4ths and 3rds, the different chord forms are closer to one another on the fret board as opposed to the 5ths of the mandolin.

    Your shapes certainly can help generate moveable forms and reinforce the 5th relationships of the mandolin tuning.

    There's something vaguely similar as far as I've seen, in how you can move chords up the neck.

    If you would use the chord shapes of:
    A 2245
    G 7523
    E 4224
    C 7455
    D 7452

    and move up the fretboard.

    For example, G would use those same shapes moving up the fretboard as follows
    0 0 2 3
    7 5 2 3
    7 5 5 7
    7 9 10 10
    12 9 10 7
    12 12 14 15 [repeat of first]

    All G chords, which should allow you to find one to work with wherever you happen to land on the fretboard. Slide around as needed for any key.

    Or am I missing something or is this what you're looking for?

    I think the CAGED approach makes more sense to someone who plays guitar and has used it in the past. For a mandolinner like me it doesn't seem to simplify things.

    I'm not sure whether it is you or I who is missing something. I think a little of both. I understand that chord shapes in one part of the fretboard make different chords in other parts of the fretboard. I guess I am really just talking about labling. A name like "C shape" sticks with me better than one like "First Inversion".

    I have been working with Mike Marshall's Chord Book, and he shows the three easier voicings I show, leaving out the A/E voicing (I emailed him, and he said he uses that one too). You can see in his examples how the various inversions can be played as open chords, and moved up the neck, but he talks about inversions, rather than the open chord shapes that are the basis of each voicing. I guess part of it is that CAGED is a great mnemonic, whereas "CAGEb"--not so much. Part of it might also be that a lot of mandolin theory comes from violin theory, where chords are arpeggios, rather than grips.

    Here's a good example of what I mean by "visual learning".

    I think shapes and distances when playing the mandolin. If you're a "shape thinker" too, this might be of some use to you.

    Pickloser,
    Thanks for posting. I have been learning the theory, but having trouble putting it effectively to use. This is very helpful.

    A few years back when I was taking lessons, my teacher taught me CAGE for mando (not CAGED - no D shape for mando). He tought there where 4 chord shapes and we went over how they transitioned up the next.

    For example - The A (2245) - then make the 4 fingure G shape (7956) to make another A - and so on and so forth up the fretboard - starting from any of the 4 shapes. I had notes of all the single note positions in each chord shape for scales - and pentatonics for help in jamming. Unfortunately, I've lost these and been looking for a similar resource online.

    If anyone knows of a spot for me to find this, please post.

    Good thread!

    Where the CAGED system gives you multiple ways to play chords up the neck on guitar, I think of a similar group of shapes on mandolin.

    In my mind, they amount to:

    1. The C chop shape: 523x
    2. The A barre shape: 2245
    3. The G chop shape: 7523
    4. The E barre shape: 4224
    5. The D 'Mon' shape: 245x

    These all move all over the fingerboard, and even spell CAGED.

    Minor alterations of each will give you convenient 7 chords and minor chords.
    Pretty much all you need to "rhythm jam" with others.

    (P.S. Similar to what Markus said, with a few differences.)

    Mike Marshall's DVD #2 covers this in spades. Very well done DVD. Highly recommended.

    Pickloser,
    I can't thank you enough for your guide to double-stops - they were a revelation. I, too, think in shapes and patterns. The way you presented everything along with names for the various shapes made this stuff easy and obvious for the first time. This is quite a resource and I hope more people download it and use it.

    Phil

    The wonderful thing about these instruments is that they transcend every "system" we come up with to learn them.

    I have just discovered the value of barre chords (see thread), which I have been avoiding for years because of how I had to change my hand position to accomplish them. I have played up the neck without them for a long time, and kind of resented having to "drop my wrist" to a guitar type hand position to do them well. Now I am exploring what I can do (could have done) with barre chords and the "portable nut" way of thinking. So far it doesn't make anything easier (I still hate the wrist drop), but it is a new way of looking at the fretboard. The mandolin is new again.

    The mandolin just is. Our human brains require these systems of nomenclature and tonal relationships to make our way, but the mandolin transcends them all.

    This is so helpful. I am a newbie, and I have been going over so many explanations of this exact thing!! I think that there is a mando lessons tutorial video on this. I like to compile though, and learn from multiple examples and explanations. Thanks soooo much Pickloser!
