Erik-Jan van der Hel is a Dutch organist and composer. He is organist of the beautiful Reil organ of the Immanuelkerk of Ermelo. He wrote five beautiful baroque variations on the Genevan Psalm 43. The variations are dedicated to me, which is an honor, especially when the music is so good. I fully recommend to play this piece yourself, certainly when you're organist in a church where they still use the Genevan Psalter in services. Variation 1 can be played on two manuals or one manual. I did both, also playing variation 1 at the end as closing chorale (plenum).
You can find the timestamps of the variations on the timeline of the video.
