Songs With No Key Center

Ok Ok blues (in its most basic form) uses dominant sevenths but what is a dominant seventh only a major chord with the dominant seventh included

Blues in pretty much every form uses the V7 chord. Aside from the Herbie Hancock style blues tunes using V7sus chords I cant think of any blues that doenst use V7 chords... altho this doenst mean much cause I ant no expert on no blues

And sure a V7 is a major traid with b7 added, but that b7 kinda changes things a little. I certainly wouldnt treat a major triad and V7 chord in the same way and they defeintley dont sound the same to me!

The whole minor scale wouldn't sound "pretty out" over a major triad. Although A minor 3 played with a major 3 would sound out if it was sustained which i think is what your getting at, thats just one note though. The third of the minor scale can be played as a passing note or bent up to a major third(or beyond).

Sure you'd getaway with the 2nd, 4th, 5th, M6th... but none of those notes outline the harmony, so until you play that min3rd you're not playing a minor scale! And as soon as you play a min7th you're outlining V7.

I like to use tri tones when i play. If you play a sustained tri tone to someone they would just wince but it can be effective if used right, especially when it comes to funk. (check out the simpsons theme when they sing "The Simpsons" at the very start a good example of a nasty sounding tri tone working well) I know tri tones are way off topic but what im getting at is something that sounds nasty or you might think sounds nasty doesnt necessarly always sound nasty

Call me old fashioned, I wouldnt play a minor scale over a major triad unless I wanted it to sound very out. The third in the major triad is the most important note, the only note indicating the harmony of the chord. I'd say in 99.99% of cases a bass player would be best to support that.

The Simpsons theme uses a diminished half whole scale, so there's more than one tritone in there

Or a minor chord with a 7th... and you can also play the minor sixth over a major chord

By itself the third really dosn't mean much at all, you need 3 tones to be able to define a chord...

I guarantee if you play a minor 3rd over a major traid in 99% of cases people who have heard any form of western music before will think you played a bum note. Passing tone or other wise, it will still sound out.

So you say I shouldn't use any chromatic passing tones either??
