Schumann Rosemunde, Beethoven, Humorous Hayden & J.Hisaishi

Kia ora musos,

We won't have a violist or 1st violinist for this meetup. People are travelling overseas or in the ASO concert next Sunday (19th October)/

Can anyone suggest any ideas?
Is there music where the viola part is rewritten for a 3rd violin? OR
Ask a violinist and violist from orchestra?

I'd be glad to hear any ideas you have.

Thanks!
Rewa
