What's a dozen, dozen? A gross!
The standard blues progression has 12 bars. Play it in any key. At the end of 12 measures, modulate up a half step and do a new 12 bars. Repeat by half steps till you're back to the original key. 12 bars times 12 keys...voila
"The Gross Blues".
Great exercise
Cool way to modulate...keep your hands in constant relation to the earth but raise body by your toes. The Stick elevates and you're magically playing a half step higher.
Bend your knees to descend the key

144 bars, that's a lot of drinks and a staggering "Gross Blues"! I'd take another route home. Instead of chromatically ascending modulations after every 12 bars (whew), I 'd move "forward" in 4ths around the circle of 4ths/5ths. Same 12 times 12, same amount of drinks at each bar on the way home.

Another path taken sir. Instead of going up a fret on modulation, we go across the strings and sometimes back 2 frets. Mental geography. A study in GPS playing. Good alternative study with very different sonic results.

Yeah... I woke up this morning thinking if there was a way to never repeat the same interval in modulating before reaching the end of the 12 keys cycle...

There's a challenge!

C - m2 - Db - M2 - Eb - m3 - F# - M3 - Bb - P4 - D'oh! I'm at Eb again.

OK, um, #4 - E - p5 - B - m6 - G - M6 - oh no I'm at E again.

OK, m7 - F - M7 - back at E. hmm...

I got to nine keys that way. Fail.

I adipose exercising the Gross Blues it aggregates a chromatic condition I have.

Oh I wish I'd wake up thinking about that , rather than getting a ship to timor from Indonesia & back again....but I do have a Stick with me. You better still be coming up with a way to meet again in France Rodrigo

...what's the goal to do like this?....
...sounds it better in any way?, or it's a task for chess players?...

Actually I was thinking more in terms of coming up with different ways to modulate. The less obvious the modulation the more interesting it is: skipping the obvious “going to the dominant of the next key”. Have you ever had to do an arrangement of a song for two singers where you have to change into a real non related key, in the middle, and do it in a beautiful way?
