I’ve read about “bowed” keyboard instruments from various sources. I never thought I would witness such a thing becoming a reality (at least in cyberspace):
Here we see Sławomir Zubrzycki (pianist, composer, and instrument maker) performing on his recreation of Leonardo da Vinci’s “Viola Organista”. To say that I don’t want to have one (or at least be able to play one) would be dishonest. Maybe I should consider writing a work for this instrument.
I would say that the instrument sounds more like a viol consort from the renaissance rather than today’s string ensemble. Would this replace the modern string quartet? I don’t think so, but it sure is a unique and cool instrument.
