So far, I have only, on occasion, used the #1 button in a fat G chord (1'3'6')at the end of a song. Is there anything else you can use it for? Anything in the push? It just seems wasted for all practical purposes.
Alexander, i have been laughed at before for reporting this, but Larry Miller told me (and it is written in his book YOU CAN PLAY CAJUN ACCORDION) that the #1 key was used in the old days to retune your accordion when it needed tuning, and had no other purpose back then
Larry told that story to a lot of people. Then as they were exposed to more professional musicians they realized he was not telling the truth. Quebecois players use it all the time. Besides if you don't feel comfortable using it make believe it's not there. ]
