Here's a little something I whipped up earlier this week, and I'd love to share it with all of you for Christmas. May it help you find some peace in this season!
The piece is built on the motives at the beginning and end of O Come, All Ye Faithful. It starts quietly with the celestes and Jubalflöte, then builds in intensity, with a sudden chromatic modulation along the way. The theme "O come, let us adore him" is stated almost verbatim from the original tune before the piece reaches a quiet ending.
I'd be very happy to hear any constructive criticism. (Note: my Hauptwerk organ has no pedals—the pedal note at the end was overdubbed.) In improvisation, I consider myself a student still with much to learn!
