This virtual claviorganum is real fun to play. Pieces from the Fitzwilliam Virginal Book are perfect for it. I've tried to create a medieval atmosphere by using the lute in combination with a flute 4'. Add a little bit of reverb and you're in a castle, dining with Richard the Lionheart, entertained by a troubadour and recorder player :)
I knew the song 'Watkins Ale' from a wonderful recording of Ensemble Phoenix Munich. Listening tip: https://www.youtube.com/watch?v=F1sC90mqxZg
The composer of this version of Watkins Ale could very well be William Byrd.
II: Cithara (Lute 8') + Amabilis (Gedackt 4')
Repeat only the Cithara
