Gerrit Stulp (1935-2019) is a Dutch composer. He mainly composed choral works and organ works. This piece comes from the bundle Noord-Nederlands Orgelboekje (free translation: small organ bundle from the North Netherlands). In this bundle you can find some beautiful choral preludes, mostly in a moderate modern style, which are good to use in services.
I use the trial version of the great sample set of the Weigle-organ in Nagold, sampled by Pipeloops. You can use all stops, but when more than 7 stops are used, the sound is muted periodically. Quite a challenge ;)
