I have a guitar question. I want to know what to use to solo over a Blues progression that are all 7 chords.?

Alright, so in my jazz band, we don't do very much down to earth power chord blues progressions, but instead do blues progressions with all chords being 7 chords. In a power chord blues progression I'm very comfortable soloing using a pentatonic scale over the entire thing, which is a nice shortcut because I don't need to think about the changes and focus on making a bluesy melody. When I tried that with the 7 blues progression, maybe it's just me, but it just doesn't work. The sound of a power chord with the earthy pentatonic sound fit together perfectly, but the 7 chords give it more class and really don't bond well with the pentatonic. I of course explored possibilities, and started playing the changes such as (on a Bb blues) Bb Mixolydian, Bb Dorian, C Mixolydian etc. This is distracting and I wish I could rip on this 7 chord blues like I can rip on a power chord blues w/ the pentatonic, but I can't seem to find a way:-/
Any suggestions anyone could give will help. thanks!!

Dude, you're kind of thinkin' the feel right out of ANY song, let your ears be the judge.

if You can handle VERY good the pentatonic try to stay in it.

You may be using the wrong harmony.
the key signature allways refer to the melody.
Your strng instrument is concert keyed.so,if You see F mayor(one "b" in the melody,treble cleff You will end up playing the D minor flat in the harmony staff.)
play the D minor for harmony or You gonna crash on the sax's guy (I think that is what happening to you)

but,do not take me for granted,I am a weekend wine piano BANGger. just check that out.

Remember that' normally' in music you have to resolve to the tonic which will most probably be not a 7 chord as it has a tendency of unrest.But anyway,Try using minor pentatonics and some 'blue notes'very sparsely.Eg A7( chord minor pent.use Eb and Bb)these will not sound good if its played for a lengthy time,but awesome if its done momentarily,also passing notes(chromatics)second chord changes to D7...use the above scale again,same for the last chord E7,it works fine.Keep going around the neck as not to make it boring..small phrases..leave enough space in your solos..look at the bebop scale..its very interesting.Stop for a second and Think,sing some little riff that rhymes in your head,then look for it on the neck.
One NEVER stop-s learning,it would be so sad if we knew everything!

You want to listen to how the greates played blues and jazz- just search 12 bar blues by ANY musician, theres millions out there.

As for the theory aspect, DONT play scales over certain chords, it just leads to disaster and sounds like crap. Yes, I said it. Playing scales over chords sounds like crap. Jazz musicians approach the chord progression, not the scale.

Not what you can try is, oh say for example you're playing

Bb7 to an F7

What you can do is take your pattern in Bb, say you play the notes Bb-Eb-D

Over the F7 chord you can play Bb-Eb-Db

It's very, very simple- whenever you go to a IV chord from the I, just make your pattern into MINOR. It works great.

Other things you can do to make your soloing better- hit lots of Minor 3rd and b7 notes. The minor3rd works great over most blues applications, but try to do it over Dominant7 chords as opposed to Maj7.

Theres also the 3-7 relationship- the 3rd of the one chord becomes the 7 of the IV chord, so you can try and use patterns that resolve that way. Theres tons of ways to learn to solo great- pattern, sequence, and most of all, PLAY RHYTHMIC!!!!!!!!!!!!!!!!!!!!!
