While talking about picking challenges on another forum, where “seeing” what a player was doing isn’t really an option, it occured to me that a great way to test a players primary escape is simply to take a single looping phrase, and arrange it for DSX and USX simply by changing the position shift.
I.e:
d u d u d u d u d u d u
|---------------------------|
|---------------------------|
|-------5-7-9-10-9-7--------|
|-5-7-9--------------10-9-7-|
|---------------------------|
|---------------------------|
d u d u d u d u d u d u
|---------------------------|
|---------------------------|
|----------7-9-10-9-7-5-----|
|-5-7-9-10--------------9-7-|
|---------------------------|
|---------------------------|
Ignore the weirditalics and colors there, not sure what’s up with that…
…but, the first pattern is a 3nps loop where you shift it up one position before descending, and mechanically flows a lot like the Gilbert 6’s for the picking hand. If you’re a DSX player, this will feel pretty natural.
The second pattern is the exact same notes, but with a position shift on the first string, if you loop this all of your string changes happen after upstrokes.
If you have a primary escape, one of these should feel a lot more fluid than the other, and it seems like this is a very efficient way to test in a situation where you can’t actually see what someone’s doing.
