I had learned to play 2 of these "Chants sans paroles", as we label them in French. They are beautiful... to listen to, as well as to play. There are different difficulty levels so I chose "Medium". I had recently purchased a CD of the complete collection, exquisitely played by Else Von Alpenhiem. Now, I can access my favorites and try to reproduce them on my old piano, my best friend! Thank you, Virtual Music. That was the best 37$-something I ever spent!
