I am marking my student's work on the Level 8 Theory Additional Practice Paper in the 2018 booklet, and have a little question. In the first question on intervals, the student is to name the melodic intervals and then invert them in the bass clef. May students write the inverted intervals as harmonic intervals, or are they to write them melodically? If melodically, should the notes be in the same order as the original passage (eg. A to F# for the first interval)?
