How do you play that Blues outro that's in so many songs?

It's the really popular one that goes from high to low and does a little turn at the end. I know this questions is vague and sounds silly but I am also vague and silly and not all too bright. Thanx ahead of time for any help.

I think you are talking about the 'turn around".

The turnaround occurs in a 12-bar blues in bar 11.

Bar 9 is the V7 chord, bar 10 is the IV chord, and then bar 11 is the turnaround. Bar 12 is usually a return to the V7 chord right before the repeat of the whole pattern.

Okay, so there are MANY variations on the turnaround. Here is a commone one. Play the following scale steps - one per beat in the four beats of bar 11: 1 b7 6 b6 - then right to the V7 chord for bar 12.

Example in the key of E blues: | E, D, Db, C | B7 chord ||

Or - try this one: | D, Db, C, B | B7 Chord ||

Try playing those notes on the "b" string while also playing an open E simultaneously.

Good luck, and have at it!

In the key of E it would be E A G E
First bar Half rest, Sixteenth rest, "E" sixteenth, "A" dotted quarter note "G" sixteenth, Second bar "E" quarter note, quarter rest, half rest. Repeat.

I think I know what you're talking about. It is a little hard to explain here. If you ask any guitarist that has played for a couple years, they may be able to just show you. It isn't too hard.
A lot of times it is in the key of E. After the run from high to low, using the third string and first string, you make a little run up to the B7 chord. The run is on the 5th string. You should have someone show you though.

I think the one you mean is where, if you were playing a 12-bar in E, as guitarists do, after playing B7in bars 9 & 10 you run down on successive beats Adim, G#dim, Gdim, F#dim| E,A7,B7 - | It works both strummed and picked string by string in triplets.
