1. Teenagers cannot have the Blues. They ain't fixn to die. Adults play the Blues. In Blues, adulthood means being old enough to get the electric chair if you shoot a man in Memphis.
2. Blues is not a matter of color. It is a matter of bad luck. Tiger Woods cannot have the blues. Sonny Liston could have the blues.
3. I don't care how tragic your life is or may have been, if you own a computer, you cannot have the Blues.![]()

A little bit of knowledge never hurts,

In your case, it may be a very dangerous thing.
My point was not that blues shouldn't be written down... Though I mostly believe that ...but rather that questions like these arise when we attempt to explain music with western theory that did not evolve in said tradition.
I hear 'ya.
My point is just to clarify that in a musical context either in Blues,Jazz or Pop this situation is better written Eb7 then D#7 for reading and function purposes, and there is nothing wrong about my musical ability to know such thing. This knowledge doesn't make me a bad Blues player

Thanks for the replies.
So just moving the V7 up a half step would be considered a substitute dominant?
I thought a substitution was built off the tritone. (I've been trying to wrap my head around that).
It's the secondary substitute dominant of V, or a sub V7/V
this is why people don't write down the blues
I know, Marc. I dunno about you, but when I get them blues, it's all I can do to play 'em, let alone tryin' to write 'em down. That would kinda ruin the vibe anyway doncha know.![]()
Plus how are you supposed to read after that many Old Style beers?
Not to put down the OP at all but I have played quite a few blues gigs in my day (being from Chicago and all). I have never seen a chart for a blues tune. I actually think there might be a city ordinance against the use of music stands in a blues club.
Blues has always been an aural tradition. Discussions like this one always pop up every time we try to codify it. Most blues guys would laugh if they read this thread. Part of teaching is preparing your students for the real world.
In functional harmony, a secondary dominant chord is a 7 chord which is not being played on the 5th degree of the key centre. For example, in the key of C, the only 7 chord that remains diatonic to the key signature is G7, In F the V7 is C7, in Eb it's Bb etc. However if you look at a lot of jazz standards you'll see a lot of 7 chords which are not diatonic to the key. These are called secondary dominants and extended dominants. The most common use of a secondary dominant is in the old reliable III-7-VI7-II-7-V7 turnaround. Technically when the VI chord is played as a 7 chord instead of a minor 7, it is not diatonic to the key, which makes it a secondary dominant. As a consequence of this, when you see a VI7 in a III-VI-II-V, it's not a VI7, it's a V7/II (because it is the dominant chord of the 2nd degree of the scale). I apologise I know my answer is long winded, I really hope it was helpful.
To answer your question though, this is why I call it a substitute secondary dominant:
If the tune is in G and you're playing an Eb7, then first and foremost, the most obvious thing about this chord is that it is a tritone substitution, for A7.
A tritone substitution is what the name says it is, A substitution of any dominant chord with another dominant chord which has a root a tritone away eg.
/D-7 G7/ Cmaj7/ can be substituted with /D-7 Db7/Cmaj7/
This because G7 and Db7 (or any other two dominant chords a tritone apart) share the same tritone on the same chord tones (3rd and 7th)
G7 Db7
1. G 1. Db
3. B 3. F
5. D 5. Ab
7. F 7. B
Now since the Eb7 is a substitute dominant for A7, the next thing to note is that A7 is not diatonic to the key of G, and so it is a secondary dominant. A7 would be the V of D, D is the 5th of G and therefore A7 is the V7 of the 5th degree or the V7/V. Which makes Eb7 the substitute secondary dominant or sub V7/V
Any clearer?
Anyway, the blues is a modal progression and can't really be explained by functional music theory unless you claim the key is changing every other bar.
SO damn bad after reading all that (let alone, understandin' it) that I'm goin' out. Don't try to talk me down....first, I thought of a nice relaxed out with a bottle of Valium....no way. I don't deserve that.
I'm goin' with the razor blades.(I did think of the real SLOW out with a dose from a diseased hooker, but I can't handle that amount of time no more....) (BTW, the tune is "Everybody Wants to Go to Heaven" by Albert King--original in Ab. The passage in question can be heard at the beginning of the iTunes sample).
And here is the answer to your question. Listen to it and learn it.
I'm not criticizing your wanting to understand and write it out. I'm just giving you my real world experience. When I have done blues gigs and I tune comes up that I don't know the guitar guy will usually just play a chorus up top and you just pick it up by listening. Most blues tunes have such basic changes you should just be able to hear them on one pass. If you can't you should work on your ear.
