question about 7th chords

[DreamingTree34]

I know what a D7 chord is, but how is a D#7 played? and A#7 & G#7?

I know what a D7 chord is, but how is a D#7 played? and A#7 & G#7?

easy way to figure out, the chord generator here:

http://www.olga.net/

remember that D# is also Eb, etc. Because that's how it lists some of the sharps.

[saxman1083]

D# dominant 7 ---- D#, Fx, A#, C# (Fx=F double sharp = G)
A# dominant 7 ---- A#, Cx, E#, G# (Cx=C double sharp = D)
G# dominant 7 ---- G#, B#, D#, F#

badass chords that you should think of enharmonically anyways.

If a chord has a # next to it, you move it all over one fret to the left (one fret higher) :)

And that's a dumb way of putting it from someone that doesnt know much about theory.

man, you guys are getting ahead of me in the "Guitar Theory" thread...
I know I slacked-off this weekend.

anyway...
ok dominant 7 chords....

first of all, an A7, D7, E7, or G7 etc. chord is the same thing as saying an A DOMINANT 7, or D DOMINANT 7, etc.
dominant is the key word.

I say this, because a D7 chord is different than a Dmaj7 chord
(D dominant 7 vs. D major 7)

make sense?

so....
if you have read the "Guitar Theory" thread....we are working toward building major triads. (next couple of days)

a major triad is made up of the Root, 3rd, and 5th notes of the key

well,
a MAJOR 7 chord is the Root, 3rd, 5th, and 7th notes of the key

a DOMINANT 7 chord is the Root, 3rd, 5th, and b7th notes of the key (flat 7th)

BOTH of these types of chords are DIATONIC to the key you are playing in.

The MAJOR 7 chords happen on the I and IV chords of each key
The DOMINANT 7 chord happens on the V chord of each key.
(the ii, iii, and vi are minor and the vii is diminished)

now this is huge:
something you will see in western harmony a lot....
a DOMINANT 7 chord almost always wants to resolve BACK to the I chord in the song.....
a V chord to a I chord progression is HUGE.


anyway...that's a much bigger answer than what the original question was for....but simply saying "hey, just look it up on the chord generator" won't get you jack-shit
(ok...here I go again...this puts ants in my pants)
if you want to simply look shit up on the chord generator forever, rather than truly KNOWING what you're playing.....go ahead.
it won't take you very far.

(jumps off the soapbox)

I'm off to post more in the Theory thread.....
anything that I didn't define here or if it doesn't make sense....I'll eventually get to it in the theory thread...
we're building up to these things.

EDIT:
forgot to answer the orginal question.... :lol
take what I've said above and make it sharp....that's where the (#) comes from.
making it sharp means you move it UP the neck by a half-step.
Remember....up the neck means up in pitch.
