Yes, the Theorbo is a “larger lute” which (at least here in Germany) is increasingly being used in baroque orchestras alongside the harpsichord and a small organ as a Basso Continuo instrument. I think I first discovered it about five years ago and am always delighted when it is used, for example in Handel's Messiah. It lends such warmth or even a “Mediterranean feeling” to the accompaniment that it surpasses the somewhat “boring” harpsichord and organ, which are unable to play dynamics, while they are needed for rhythmic and percussive accents (the harpsichord) and harmonic filling and foundation (the organ).
That in mind, I decided - after nearly completing the instrumentation of my Prelude IX in E major as submission for the 2025 Christmas event - to create a Basso Continuo part, too, to emphasize the Baroque orchestra character. I must admit that it was a larger effort than initially expected (and my figured bass „numbers“ might be error-prone), however I really enjoyed the result so that I came around to present it as an „own piece“ here since I think it is worthwhile to hear it without the other instruments, which otherwise so strongly dominate the Basso Continuo that it's usually only perceived subconsciously.
Thank you, @chopin, @Luis Hernández, @Henry Ng Tsz Kiu, @Kvothe and @PeterthePapercomPoser for confirming my belief that the atmosphere of this trio is calming and it could be indeed played on its own in a church, for example during evening prayers.
Oh, I must say that I neither had "Where Sheep May Safely Graze" nor „Sleepers Awake“ in mind (while being wonderful) when composing the prelude, my inspiration was the „Sinfonia“ from the Christmas Oratorio. But, yes, if there are feelings of quotations from Bach, that is intentional (and fortunately, Bach won't be making any copyright claims...).
