Re: accordion notation - counter bass note

[Gianmaria Lari]

Perfect!!! Thank you David!

Now, because they are a bit verbose, I would like to create a function with parameter. 

This is without parameter:

\version "2.19.60" 

newFinger = \markup \underline \finger 3

{\clef bass e,_\newFinger }

How can I write somethingl ike:

\newFinger #3

?
