Re: Accordion notation: registers, stradella / ask for existing symbol modification

[Ledocq-Boccart]

Hi George,

I have searched for literature about accordion register symbols and I 
got the following link

http://64.233.183.104/search?q=cache:cpv7SYD8hngJ:www.accordions.com/index/art/stradella.shtml+accordion+register+symbol&hl=fr&ct=clnk&cd=1&gl=be&client=firefox-a

where symbols presents 3 lines inside a circle.
(with \musicglyph #"accordion.accDiscant"
we get two lines; and you should instead desire one line)

The existing
\musicglyph #"accordion.accDiscant"
symbol is sufficient for an accordion featured with max 3 voices on each 
keyboard (lets us say treeble, medium and bass)

The attached document presents 5 possible separate voices combined in so 
many registers (I believe more than 25 possibilities).
If using only two voices, only two dots are to be marked in the symbol.

_The 3 lines symbol could appears then to be more standard than the 2 
lines one_.

I presume a new glyph asks to be developped and implemented in Lilypond 
to implement the 3 lines symbols; and so requesting programming 
ressources and time to the developpers.

Could someboby among the developpers have the possibility to modify the 
existing symbol?

Thanks in advance for consider this demand!

Best regards

Charlie

ps:
I wonder how the existing symbol
\musicglyph #"accordion.accDiscant"
could be featured with one more line?
As I am interested to understand a bit more about Lilypond "deep" 
programming I am ready to invest of my time to develop that 3 lines symbol.
Could somebody among the developpers tell me where I could find the 
source of that symbol?
Or tell me if I can forget that idea?
also: my native langage is french
