in question 1(a) on the grade 6 theory paper, is it all right to have iib - V as an imperfect cadence in the first half of the piece?

Does anyone know the answer to this? My exam is tomorrow.

ii - v is okay , not sure about iib though .

I don't know if this will help:
imperfect chord progressions - iib - ii - v; 1c - v; ivb - v.

It also depends on the melody notes of course.

Thanks very much.

I think iib V is good as an imperfect cadence half way through a piece. It's weaker than ii V in root positions but I think that's okay. Thinking about it - if it is a progression that goes iib V then 1 for a perfect cadence it is a very good 'stock' progession to use.

Just played it on the piano in C major and iib V gives you a rising stepwise pattern in the bass F to G. It is very good to counteract this with a falling 3rd in the soprano line - say D to B as it helps to avoid consecutives to have movement in contrary motion.

It's good for me to try and articulate the above as I am reviewing all my harmony practice for Grade 8 theory (or Practical Mus) for later in the year. If I am off beam at all someone please correct me.

Thanks BusyBee.
