As a result of a commission by the American composer and organist Carson Cooman, I composed three pieces for chamber organ. In order to make publishing worthwhile for a publisher, I composed another five pieces. The last three of them being composed in memory of John Scott.
All of the pieces are suitable for organs with only one manual, no pedals and only one stop. The range is limited to 4 octaves and 1 step. (C great- D2)
The difficulty is Moderate.
Of course these pieces can also be played on organs with more possibilities!
The complete versions of all the pieces of Triptych can be seen on Youtube. Use "Ad Wammes Triptych" as search word and you will find your way around.

1. Les Cloches I
