Here's an upload for the beginning organ students on CCH. It's taken from "The Progressive Organist" Book 2 - edited by C. H. Trevor (published in 1959 by Elkin). Score attached - with my pencilled markings for fingering and pedalling. MIDI file also included. Some LH and Ped moments are a bit tricky, but careful repetition of short sections following the markings exactly will pay off. Watch carefully for where each part is released, especially at the ends of phrases.
Buxtehude wrote many short, expressive preludes based upon Lutheran chorale melodies. This example, based upon an Easter hymn, follows a favourite texture which places the cantus firmus in the soprano part, often ornamented and embellished. The accompaniment parts weave an intricate counterpoint beneath, drawing directly upon the chorale melody itself for its motifs.
I've used the Poblet sample set. Registrations as follows:
RH (CF): Hauptwerk - Principal 8, Octave 4, Quint 2 2/3, Trumpet 8
LH: Ruckpositv - Prestant 8, Bourdon 8, Octave 4, Rohr Flute 4, Doublette 2
Ped: Subbass 16, Octavbass 8, Violabass 8, Choral Bass 4 (uncoupled)
