I'm a composer and creating a new piece of music involving an oboe. I have been studying some possibilities for the oboe to create a particular atmosphere with wide interval playing, such as found in Luciano Berio's Sequenza VII.
I read that for the oboe, arpeggios and wide intervals are not very practical. However, in the piece by Berio there are several measures that have rapid alternation between B4 and a note a minor 9th above or below.
- B4 and C6
- Bb3 and B4
- D4, B4 and Bb5
In the orchestration book by Walter Piston, he displays various common harmonics for the oboe, and mentions that for some of the higher, the harmonic partial is displaced an octave plus a half tone from the fundamental (minor 9th).
Are these wide intervals written by Berio, harmonics? Is there a way to determine which wide intervals can be actually played considering the oboe possibilities?
I'm looking for minor 9ths, as in the piece mentioned...
