My harmonisation attempt adding A, T, B in open score:

As a WAV file generated by Sibelius:

Looking now at the Bach original, he harmonises the ‘-angst’ in a way I would not have guessed, as the third inversion of a dominant seventh, resolving upwards with a jump upwards of a major seventh in the bass line!

Bach chorale harmonisation with high trumpet descant

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!

This chorale has an unusually narrow range of pitch and moves in steps not leaps so I found avoiding parallels harder than usual, and changed key more often than previously to try and keep up the harmonic interest.

Bach’s original:

Interesting diminished 4th leap in the tenor in bar 6

Further Bach chorale exercise worked and compared to original

Riemenscheider 129, Keinen hat Gott verlassen worked from the soprano part alone:

I found this resource for A level and first year university students very helpful and this time wrote  modulations and main cadences first:

Mine version has too many false relations but is I hope ‘singable’. ┬áThe final Tierce de Picardie is the one modification I put in after seeing the original BAch’ I’d forgotten about that option!

This compares with a recent ‘DeepBach’ machine harmonisation given in the paper:

https://arxiv.org/pdf/1612.01010v1.pdf

and a different, better example from the same tool in this video:

 

The DeepBach tool does not check for parallels but is quite impressive.

Boyd Bach chorale composition exercise 2, Herr Jesu Christ du hochstes Gut (Reimenschneider 266)

As set (this time using short score):

boyd-chorale-exercises-2-bach-266-herr-jesu-christ-as-set-full-score

As attempted, not idomatic and with octave parallels weakly avoided by suspensions

boyd-chorale-exercises-2-bach-266-herr-jesu-christ-as-worked-provisionally-full-score

Last note for alto should probably be B flat to supply a third to the tonic chord

As written by Bach but note crossings twice of tenor and supplied bassparts!
