Flicking through my practice book tonight I came across this short and interesting piece.
It was composed by Johannes Barend Litzau (1822 - 1893) and is part of a collection of 32 short and easy organ preludes. And they really are short.
I like the piece quite a lot (and not just because it's easy enough to play it without much effort) except for the end, which somehow feels "not quite right". Almost a shame this piece is so short.
