The arrangements I have written thus far for my Wedding Melodies Series have utilized just the violin and the violin and cello; please see Wedding Melodies For Two Violins, Both Bound Physical Books and PDF Downloads, Wedding Melodies For Solo Violin, Both Bound Physical Books and PDF Downloads, and Wedding Melodies For Violin and Cello, Both Bound Physical Books and PDF Downloads. 

But in the future, I hope to broaden my instrument selection to include among others, the viola and violin. Much of this, however, will be determined by what the demands are in the marketplace.
