Issues covered at supervisory meeting: The adaptation of the text. Narrative theory. Some differences in singers producing different vowel sounds at different placements in their range. We discussed, and looked at, the “vowel chart”. Ritual in the Jewish festival of passover and if it might find a place in the opera. We discussed different composers approach to compositional technique (pitch class sets).
In my original proposal for PhD I had mentioned trying to use "non-lexical vocables" which are inspired by the band The Cocteau Twins use of an "invented language" to use which services the music (rather than text being set to music). In order to generate vocables in the style of The Cocteau Twins I asked chat GPT to generate some, It took a while to give the right prompts to the Artificial Intelligence but, eventually, it came up with something close to what I was looking for. Below is a link to the conversation which led there. Below that is how I set (as a hocket) the text the AI gave me.
