This published collected edition consists of two different pieces
1: Opus 35 written in January of 1987 and revised in the year 2002 is in four
short movements.
2: Opus 135 is one long movement that get faster throughout. I am including
parts for each instrument because of the difficult page turns in the score.
I think the opus 35 is easy to put together, but the opus 135 looks difficult
but would be worth working up for a recital.
Each copy copies is just $4.00. You might want two copies for yourself and
your duet partner.
