Alt Chords.

I know how these chords are made; and their structure in terms of intevals as well.
I even know how to play those chords all over the fretboard.
My question is. How in the world four different type of chords have the same name?
For those who don`t know what I`m talking about, I`ll list the chords in a generic way:

Alt=[1,3,5b,7b,9#]
Alt=[1,3,5b,7b,9b]
Alt=[1,3,5#,7b,9b]
Alt=[1,3,5#,7b,9#]

Can somebody explain this?
Thanks in advance.

Hmmmmm
where is everybody?

Can you give us the name of the chords?

If, however, you mean Alt is the name of the chord, I suspect Alt simply stands for "Alternative"; either another way to play an already mentioned chord, or a chord you can use instead of the the one normally played.

Alt stands for Altered.
And the name for the four chords I mentioned before is Alt.
So if you are playing the fallowing chord progression:
Dm7,GMaj7,CAlt
Which one would you play at the end? And Why?
My original question was. How come the four type of chords have the same name; when their formula and structure is different?

And not all those chords are compatible with the Alt Scale.

I'm a bit rusty in my theory, so I'll gladly retract this if someone can tell me otherwise, but...

If I recall correctly, an Altered chord is simply a generic name for chords that go beyond "Extended" chords - they have their own specific name which is often forgotten because of the theory involved behind them. Alt isn't necessarily the name of the chord, just an indication that it is non-standard (root, 3rd, 5th), or extended (root, 3rd, 5th, 9th, for example)

I believe Dominant and Diminished chords are classed as Altered chords, where as Dsus4 is classed as an extended chord. That would explain why you can have the same chord "name", even though the theoretical structure is different.

There's more theory behind all this which I can go into if you'd like, but I'm hoping that should be succifient to answer your question

I'm 99% sure that's right - would anyone care to prove or disprove the remaining percent?

Hope that's of some use...

Hey.
I really apreciate you taking the time to answer this question.
But unfortunatily your theory fails in the fallowing:

1._You said that an Alt chord is a chord that goes beyond extended chords.
Well, many chords go beyond extended, and are not consider Alt, for
example:
13#11=[1,3,5,7b,9,11#,13]
-13#11=[1,3b,5,7b,9,11#,13]. etc
2._You also said that Dominat and Diminished chords are classed as Alt.
Not true. We have a group of chords that belong to the Dominant type.
But each chord has an specific name, for example:
7
-7
7sus2
7sus
7b5, etc
And for the Diminished group:
o
o7
1/2 dim, etc
Do you see how each chord has its own name?

3._ You said that a Sus4 is classed as an extended chord, and that is not
true eather.
A chord of the sus4 type; uses three notes of the scale:
Sus4=[1,4,5]
it belongs to the "Suspended Chords" group and each chord has an
specific name:
Sus
Sus2, etc.
Again. Do you see how each chord has a name?


So here we go back to the original question. Why those four chords, which are different in structure and quality have the same name?

I did say I was a bit rusty...

However, I have found this definition that, although very brief, should explain it

http://www.google.co.uk/search?hl=en&lr=&oi=defmore&defl=en&q=define:Altered+chord

Think it's time for me to step away from this conversation and let someone who's not forgotten half the stuff have a go...

Again, thanks for replying and for the link.
The info. in the link tells what I already knew. That an Alt chord is a Dominant chord [1,3,5,7b]. And then the alterations occur in the (5th) and the (9th) degrees of the scale.
But it dosn`t explain why the four chords have the same name(ALT).
I guess my question is gonna remain with no answer.

???????????? :confused: ????????????
Damm jazz fusion chords ..........
.....maybe it has to be with melodic secuences(voicings), you know like a decending bass line or if it is used like a dominant chord to jump to another weird chord or tonality :confused:
