This is an exciting transcription of one of Bach's most famous organ works - made by a professional organist, who also happens to be an experienced brass player. It needs 8 professional players to bring it off - it taxes all instruments to the limits. It must have just 1 player for each of the parts A-H Various alternatives are available for all 8 parts and will work especially well with either all brass band instruments (e.g A = soprano Eb cornet, B and C = Bb cornets D and E = Eb tenor horns, F and G = Baritones (or euphoniums) and H = Eb or Bb Bass) or all orchestral/military band brass combinations. Really virtuoisi trombonists could try a baritone part!!
