I do weddings year round, and these days people are not hiring a full string quartet very often. So we do Duets-- this little collection has mostly the pieces I already had in other layouts, but I prefer the crisp clean page layout given here. The Tartini Cantabile I had never seen before, and it is very welcome addition for Prelude music. The Albinoni Adagio--IMHO I would never play at a wedding, too angst-filled. To improve this product it should include more, lesser-known Baroque pieces, perhaps VSM will make a Volume Two of these duets (I also use Violin & Cello, Violin & Viola). Then I will give it 5 stars!
