Major 7th chords

What's Hot
Cmaj7 or C <little triangle> 7 pleez.

"CM7" is bad enough in print (even though you're supposed to suss from the upper case that Cm7 is not meant) but in handwriting - if you perpetrate it you should be shot.

Anyone else hate the M7 notation?

  • Maj7 chords are for sissies anyway so who cares?

  • If liking them makes me a sissy, then I'm a sissy :)

    BTW I also like minor, dominant, half-diminished, and diminished 7ths. I don't think I'm discriminatory, except for the context in which I use them ;)

    My philosophy is this: CΔ - chances are very very strong that I'm going to try it as CΔ7, CΔ9, CΔ11 and CΔ13 at least once anyway ;)

    Equally I don't bother embellishing Cm to Cm7 as I like Cm13 and Cm♭13 and seeing which does the trick.

    As for Δ7 being for wimps, try subbing a Diminished chords for a Δ7 a semitone below. 

    A sig-nat-eur? What am I meant to use this for ffs?! Is this thing recording?

  • wotyer fink of the notation though @frankus? whenever I see 'm' (or even 'M') I read it as minor, and then have to perform some kind of mental correction because somebody has used upper case to mean major. and in handwriting, it's just effing ambiguous!

    I always use a delta, most of the fake books I've ever used, use a delta for major or Maj. 

    Band in a Box uses " Maj" which is clearer than an upper case M.

    I don't like capitalisation in notation, although at one stage I used to write Nashville notation thusly: iii iv ii V I - I got told off by Dario Cortese :D

    Are we talking maths here with all these triangles? ... C and the rate of change of 7, C and the rate of change of 9..  my head hurts.

    Cmaj7 chords are lovely happy spring bright things that should never be hurt and should have their own happy smiley thread...anyway!

    Yes, the triangle sign (Δ) is popular, I think the triangle originally signified a triad.

    I was taught M7 can be read as minor7, so to be clear it's Maj7.

     

    I think I've played a Maj7 once in the last 5 years.

  • Just to be clear: Cmaj7 should be written that way or as CΔ7 ...

    ... but NEVER as "CM7"

    Anyway, I've only ever played Maj7 chords when playing old Jazz standards. I never play the fifth with a Maj7, so adding more flexibility for the soloist. With a band, you really only need two notes the 3rd and 7th.

    For Example ::  G minor 9 is made up of ;  G, Bb, D, F, A.

                             Remove the Root Note (G) and you are left with Bb,D,F,A,, which is Bb Major 7 !!

    Egad Sir, you're right. A different "hidden one" which I use a fair bit (and which, tbh, should have come to mind when I tried to think  about your example) is B-7-5 as a substitute for G9, again losing the root. I am slowly beginning to realise the truth of what was said a long time ago at the Guitar Institute, that if you can leave the root to someone else you can create more complex sounds out of stacking simpler things on top, eg Em with a C root = Cmaj7. 'Tis something I experimented with at the time, and IIRC I made a list of what you get when you stack things on different roots, but only recently have I consciously begun to use it. Thanks for the nudge :)

    If you have a maj7 chord play a harmonic minor from the 3rd - eg Cmaj7 play E harmonic minor.

  • If you have a maj7 chord play a harmonic minor from the 3rd - eg Cmaj7 play E harmonic minor. 

    that would leave you with a #5 and a #9 with respect to the C. OK if you want that sort of thing, I suppose ...

    Lose the M or m if you're using the Δ sign for major, you ought to adopt all of the jazz notation ....

    - minor
    º diminished
    Ø half diminished / m7b5
    7 dominant

    Imagine something sharp and witty here ......

    There's only #9 and #11. E Harmonic Minor Scale : E F# G A B C D# E. The notes of C Maj7 are all within the Scale.

    Another little bit of musical mind gymnastics. You sometimes see a Gmin7 chord replacing C7. It''s just C11 (C  E G Bb D F) with the Root and 3rd removed.
