I wonder if anyone can answer this query (perhaps even Mr Sparke himself!)? Variation 1 (the loud horn one!), bars 57-66 are marked piano throughout on the music; however, at bar 65 & 66 the horns and baritones have an accented motif together with percussion. Percussion is marked at ff, should horns/bars be the same dynamic as percussion, or still just p??? Apologies if this has been asked before. Thanks!
