idea was to have more flexibility of keys, etc
which the chromatic does have
PROs:
universal, logical fingering for all keys [at least with 5 row]
(ALL instruments should work like this)
CONs:
if you learn it, you STILL cannot play the piano, which is ubiquitous - you HAVE to have your own unique, heavy, expensive, instrument everywhere you play
REMARKS:
since it is WAY different from cajun accordion, i didn;t learn it very well, i didn;t give it a fair chance, but i could see it was taking longer than i wanted
C system is most prevalent everywhere except eastern europe
though that doesn;t matter here, you won;t find C systems just hanging around either
if you got something like a roland v-accordion, you can switch it from B to C system, as well as many other (including custom) note arrangements
BUT (annoying) - still no one makes a single accordion that could do both
you can customize the v-accordions, but not to have in and out play different notes @#$@#$@#$@#$@#$@#
i would almost advise learning piano, but using an electronic piano that can key-transpose easily
or accordion, computer piano accordion
just so, when you don;t have your accordion, you can at least play SOMETHING on a piano, which will always be nearby
(though by that logic you would just learn guitar which is also chromatic, 100x more portable and 1000x more prevalant than even piano)
