A more chomatic spider

As previously a warm-up and synchonization workout
instead of the classical spider (1234 1234 etc...)

-----------------------------------------------5-6-7-8-
---------------------------------------6-7-8-9---------
-------------------------------6-7-8-9-----------------
----------------------7-8-9-10-------------------------
------------8-9-10-11----------------------------------
-9-10-11-12--------------------------------------------

why not a true chromatic scale ?
with no "hole"
To be worked up and down of course, start where you want.
