This prelude is one of the six Kauffmann wrote for the combination organ and oboe. It is a lively piece in 6/8 meter. Kauffmann has a knack for writing in ternary rythm. Those pieces have something special and this one is no exeption. The oboe is used to for the choral melody while the organ plays a trio like accompaniment. A nice detail is that the oboe plays the first two notes of the choral melody three times: an eighteenth century wake-up call.
The recording is not really live of course. I first played the organ part. After that I played the oboe part and mixed both recordings.
