Hi all,
I have just published a collection of 12 renaissance duets from Italian author Gioseffo Zarlino. These duets where adapted to modern melodic instruments and for each of them you will find:
Original facsimile
Modern Notation
Modern Adaptations in C, Bb, Eb and Bass clef.

The modern adaptation was made with the melodica in mind: almost all the ranges of the 12 duets are already within the limits of a standard 32-keys melodica, I had to make a very few octave transpositions when needed.
You can play these duets with another melodica or, thanks to the Bb, Eb and bass clef versions, with many different instruments: recorders, flutes, saxes, clarinets, cellos, etc.
Here you can download a few sample pages
This is the official page on my website
And this is the link to the amazon.com page (you might have to switch to your local amazon page to order).
Thanks
