Reine de Musette notation question

[Glug]

Hiya Folks,

I've found the full score for Reine de Musette in Accordeon Facile volume 1 and there's a couple of bits where I don't understand the notation.
(key is A major / F# minor).

1) Bass note in brackets

What do the brackets mean on the C natural ?
There are other places with 'double voicing' on the bass, but B# is C natural anyway.

2) G7 or not G7

Any idea why Bm5natural is matched with Sol7 ?

Cheers,
Gareth

I believe the C natural in brackets is just a reminder that B# is the same as C natural.
The Bm5natural chord consists of B-D-F and Sol7 is G-B-D-F, which actually plays G-B-F on many accordions and B-D-F on some other accordions.

Thanks for that, it all makes sense.
I've got a lot to learn
