As the title describes, this exercise is about transposing instruments. The task is to transpose two excerpts, bars 1-5 in Don Juan by Strauss, from the written pitch to the sounding pitch.
Below is the first excerpt of the horns in E, given in the written pitch in the course material:
When played, the horns in E sound minor sixth below the written pitch, meaning that C major in the excerpt becomes E major below. I find this to be the most efficient way of transposing – not thinking about every note as a separate unit to transpose, but instead, I regard the notes as maintaining the same functions within different tonalities – tonic, supertonic, mediant etc. Also, in my ABRSM theory exam, I remember there were two ways to notate transpositions – with key signatures and without. Thus, to practice, I did both versions here, although for the ones without key signatures I still wrote the natural signs within the parenthesis:
The second excerpt is for clarinets in A, given in the written pitch in the course booklet:
When this excerpt is played, the clarinets in A sound minor third below the written notes, and the tonality of G major becomes E major below. Here are the two versions of my transposition:
In conclusion, I already did some exercises with transposing instruments, such as the ones for my ABRSM theory exam. However, I never actually transposed anything from the repertoire, which is why I found this exercise so beneficial. I also haven’t done it in a while, so this was a great refresher too, to get me back into the gear for orchestral writing.
