is there such a thing as a diminished barre chord? and is it moveable?

also with chords in a key....


Can those min be substituted for min7? and the Maj with Maj7

all with the exeption of the root.... and the Dom 7th as my 5th tone

with the A and G strings being the root note

with the G string being the root note (I find it easier to change into a major chord from this one like at the end of a major scale)

with the E/D strings being the root note (you can leave out the high E if you want)

or this is more like a "diminished power chord" and might also work

You could substitue a maj7/dom7 for a regular major and a min7 for a regular minor without it sounding bad, the other way it might clash with something (but then might work, depends on what you're working with and theres some more theory but I've never really looked into it. In an allready existing song they'd probably sound wierd but if your writing something of your own...)

edit: ah chords in a key,
here are there 7 version for the major scale:
1 maj7
2 min7
3 min7
4 maj7
5 7 (dominant 7)
6 min7
7 I've got no diea, Logz made a thread on diminshed/augumented 7 chords
8 maj7

edit2: yeah, prettymuch what you said

on the 7th chord, you could get a few different chords...

Take a look at the Locrian mode intervals: 1 b2 b3 4 b5 b6 b7

Now, usually the 7th chord is a diminished chord, because the locrian mode (7th scale) has the intervals 1 b3 b5 included, which is a diminished triad.

Also, you could add a b7 onto it to make it ½dim7, which can also be called a m7b5 chord.

Theres also a b2 there, so you could have m7b5(add b9) (1 b3 b5 b7 b9) etc.

So like seljer said:

Imaj7 - 1 3 5 7
iim7 - 1 b3 5 b7
iiim7 - 1 b3 5 b7
IVmaj7 - 1 3 5 7
V7 - 1 3 5 b7
vim7 - 1 b3 5 b7
viiø (or viim7b5)- 1 b3 b5 b7

Capital Roman Numeral = Major chord
Lower Roman Numeral = Minor chord
ø = Half Diminished

Yes, you could have a dominant 7th chord on the 5th tone, because the 5th scale is mixolydian, which has the simple intervals 1 2 3 4 5 6 b7.

Note the b7, therefore, if you wanted a chord to go over the top of it, you could have 1 3 5 b7 (Dom7) 1 3 5 (Major) and so on. As long as the chords intervals are also in the scales intervals, you can have it.
(There are other extended modes though, but im not certain on them so im nto going to go into them!)

I think thats right!

As for diminished barrechords, full 6 string barres wouldnt work because just say you took this example of a C Major barrechord:


In a Cdim chord, you flatten the E and G, to Eb and Gb. So now, if you plotted them out, you would get this:


Note how the 7th fret on B string lies behind the 8th fret barre.

Im not sure about any other barre.
Been away, am back
