Here is a quick tutorial for a fun blues turnaround. I show you how to play A7, D7 and E7. It's a twelve bar turnaround:
|A7---|----|----|----| (four bars of A7, each bar is four counts)
|D7---|----|A7---|----| (two bars D7, two bars A7)
|E7---|D7---|A7---|E7---| (one bar E7, one bar D7, one bar A7, back to one bar E7)
A7 D7 E7
As always, keep practicing, and get into playing. For a comprehensive list of chords, tips, tricks, techniques, etc, I recommend Ukulele For Dummies. Check it out.
In case you're wondering, I'm not the only person who provides a tutorial on the 12 bar blues. I hope my tutorial is clear enough to keep you from running away.
The video will help you count out this progression, but let me just write it out real quick.
What's a bar? A bar is a measurement in a song. I think most "popular" songs have a four count, but occasionally you'll find a song with a three count. Three counts are most commonly recognized in a waltz. There are other counts, but you're not going to see those in any music I'm going to teach.
We are focusing on a four count bar, and of course, the "12 bar blues" is going to be 12 counts of four. Make sense so far?
To start the practice, focus only on downstrokes, and count it out. "1, 2, 3, 4, 1, 2, 3, 4 . . ."
Using the chords C, F and G, the progression goes:
C: 4 bars
F: 2 bars
C: 2 bars
G: 1 bar
F: 1 bar
C: 2 bars
repeat.
You can do this progression with these other major chords (respective to C, F and G):
E, A and B
G, C and D
A, D and E
D, G and A
The benefit of playing the songs with different chords is how high or low your voice can go.
A few examples of songs with this progression:
Can't Buy Me Love
Hound Dog
Great Balls of Fire
There's more examples, so let me leave it up to you to tell me what they are.
