Hello, could somebody please clarify 2 questions I have about 2 of the Bach Chorale exercises in exercise 42 in Anna Butterworth's HIP book.
My first is for the exercise in C minor, R45, the chord figuration is 6 on the 1st beat, 5 on the second. The bass note is a B natural minim, so the 1st chord is G major in 1st inversion, V7b. However I was thinking the 5 would mean vii dim - a BDF triad, but the answer book shows the chord as B G D F. I assume then that the 6 5 figuration was referring to one note - 6 above the bass, resolving to 5 above the bass. Am I correct? The 6 was in the soprano and tenor part, but only the soprano part comes down to the F, it would mean consecutives if both did I suppose. If the composer had wanted a BDF chord, perhaps there would be no number 5 underneath, so a 5-3 chord would just be assumed. Anyway it's confused me a bit.
The second question is about the following exercise. R38 in A minor. The soprano line for the 4th chord of the 1st bar has 2 quavers - D-C. These are above a bass note of D, the chord being iv. I had put an F in the alto, but my next chord had E in the alto and B in the soprano (it was a V chord). The last quaver 'C' in the soprano from the iv chord is clearly a passing note, but having F in the alto, then E in the alto for the next chord, does this count as consectutive 5ths? I wasn't sure if it would since the C is not really part of the iv chord. However when I play the passage, the 5th created by the passing note and the following P5 interval do sound weak together. Anna Butterworth has harmonized the answer in a different way in the book, a little irritatingly doubling the root of a 1st inversion chord, when she clearly states earlier in the book, it's best not to do this at first, so I didn't think to do that in my answer.
Anyway, I hope my questions makes sense and appreciate any answers clarifying this for me.
