An interesting piece - thanks for posting!
Your question as to what the music might look like
I would have thought that it would not look too much out of the ordinary - it is a fairly conventional piece, after all - a melody line for the bass, and text to be spoken. I wonder what it would sound like if the text were to be sung, using the bass as an accompaniment (or vice versa
).
The scores of a lot of modern pieces look strange by conventional standards because many modern composers stretch the resources of their performer or orchestras to the limit, asking for sounds and effects which simply cannot be notated in an conventional way (I'm thinking particularly of Stockhausen) - so, the notation is evolving, much in the same way as does language.
Not wishing to wander too much off the topic here - check out the "Sequenzas" by Luciano Berio (there were 13 at the last count - he died in 2003) - Sequenza III is particularly brilliant. "Failing" reminds me of Sequenza V (trombone), which has the same sort of humour.
"Spanning virtually the whole of Berio's composing career, the Sequenzas constitute an innovative investigation into the virtuosic and dramatic possibilities of musical performance. Some of the early Sequenzas, such as those for flute (1958) and piano (1966), are classic examples of the abstract avant-garde language of mid-twentieth century music; others show a love of the theatrical which is more obviously Berio-esque, such as the instrumental buffoonery of Sequenza V for trombone (1965) or the vocal acrobatics of Sequenza III.
