This is a good book with a variety of historical Renaissance pieces for the recorder and piano. As an intermediate recorder player who plays on his own, I found the music in this book quite easy to play after a few practices. The music selections are rather short only lasting around 1 minute in playing time.
The font size for recorder notes in the book are quite small and difficult to see, but the book comes with separate pull out booklet which has a larger font.
The CD that comes with the book features harpsichord accompaniment tracks, in addition to tracks with both recorder and harpsichord playing. Occasionally the recorder musician on the CD adds a few notes that are not in the sheet music, which I personally find is a flaw. However, flaws aside this is overall a good book and it is good it comes with a CD.
