Mourning rain in Weicheng dampens the dusty ground. Willow trees give the in courtyard a fresh greenness. Why not drink one more bowl of wine? Beyond Yang Pass there are only strangers. --from Laughing Lost in the Mountains: Poems of Wang Wei; translations by Tony Barnstone, Willis Barnstone, Xu Haixin.
This is my attempt at converting the Erhu and Yang-chen score into a midi file. It has some problems with the free tempos towards the end of the piece. I've also added a perhaps annoyingly metronomic rhythm part for practicing. Please modify it if you like. I created the midi on Linux using the Rosegarden score editor. I recommend listening to Jiebing Chen's rendition of the song for a true interpretation of the rhythm.
I apologize for the messy score. That's what they look like after I've worked with them for a while! As I get time, I'll post some more readable scores, perhaps typeset with Yean-Yow's 123 program. All the fingerings and bowings come from Jiebing Chen.
