Ths is Boyd exercise 7, Riemenscheider 24 ‘Valet will ich dir geben’, a Palm Sunday hymn.
Bach set this in quite a minor way as a Pietist ‘leavetaking’ but I decided to go back to the original words which translate to ‘Glory, Laud and Honour’ (St Theodulph, 820AD).
This has a very high trumpet part which provisionally I would allocate to a piccolo trumpet in A (not sure yet about the lowest notes as this instrument may need or have an extra valve to extend its range)

Look out for the German sixth in bar 6!
