I didn't know Anzaghi's opinion on French musette music and instruments. Why did he think like that? I don't even know his method is classical-oriented. Actually I haven't finished this book to any degree. I stopped studying this book because of its lack of free bass knowledge.
But I'd checked some music pieces in this book. Their names didn't look classical at all to me, and without any instruction of the free bass system I wouldn't have any thought that this was a classical-oriented book.
So all put together, I thought this book is designed for French musette style playing, though I did knew Anzaghi is Italian (so I guess that's because my lack of common sense in different musical/national cultures
Anyway it's a bit strange if his method is designed for classical and against musette, my teachers in Taiwan should have known that (they recommended this book for me and taught me the C scale fingering in this book), but in fact they don't play classical music but lots of musette and jazz. Funny right? So maybe it doesn't matter which fingering style you've learned. You can play any music genre once you've mastered it.
To mitchnc, I am just a beginner so I can't guarantee anything, but I think both PA/CBA players can handle this song very well when they get to a mediate level.
