I saw that C Major 7, C7, and Cm7 was different than what i have learned. Here's what i've learned: CM7 - C,E,G,B C7 - C,E,G,B flat Cm7 - C, E flat, G, B flat is there something wrong?

Jazz+ -- 07/05/2007, 17:49:57 -- #35690

That's correct. Now learn the final two: Cm7b5 Cdim7

7 -- 07/05/2007, 23:42:03 -- #35690

Next add ninths and/or 13ths. And when you're done with that, investigate the fourth dimension - quartals.

7 -- 07/05/2007, 23:42:40 -- #35690

And in the minors, an 11th.

Also, note that the Cm7b5 is also known as C half-diminished 7 (circle w/slash)

all you professionals out there- is "half-diminished" common lingo, or is minor7b5 used more? to me minor7b5 makes more sense, because that chord in no way functions like a diminished chord-it functions as an altered ii chord.

khyu777 -- 07/06/2007, 11:50:49 -- #35690

o, so it's just tensions added to those 7th chords.. ah.. i c

Hi jazz guy, There have been discussions here in the past about which makes more sense, but those discussions are kinda moot since both are used :)   For what it's worht, if I'm writing a chart, it's faster for me to use the circle thingy than to write m7b5 - In Sibelius it's Ctrl-Shft-o :)

Whacky -- 07/06/2007, 14:26:49 -- #35690

*worth* not worht :)

wdennissorrell -- 07/06/2007, 16:53:23 -- #35690

I agree with Dr. Whack. It is easier to write and read for me. The m7b5 is distracting for me, but it is a matter of personal preference. Peace out!

<i>all you professionals out there- is "half-diminished" common lingo, or is minor7b5 used more</i> I prefer to think of them as different functions. If using it as an altered m7th chord in a ii7alt-V7alt-Imaj7 progression, I call it a m7b5. In a progression resolving to the minor I (ie. iiØ7-V7alt-im ), the half-diminished moniker seems to me to be more appropriate. But not everyone agrees. And not only that, not everyone knows how to find the Ø symbol with a computer keyboard [btw it's Alt+0216 ]. So the "m7b5" symbol definitely gets used more when typing. But when speaking among musicians, it seems to me (on reflection) that "half-diminished" might get more use when spoken.

Thanks, 7, for that tip: Ø = Alt + 0216
