Hello Peter,
Thank you for listening and this comment.
The orchestration is indeed a little oversized compared to the very simple purpose of this dialogue. However, I wanted to try to stick as best as possible to the words of each protagonist, namely, the woman's love/mystical exaltation, her alibi, supported by stable tones, a certain clarity of instrumentation, the organ (to emphasize pseudo piety)... in response to the rise in tension of the husband's increasingly pressing and inquisitorial questions, with an instrumentation evoking military instruments (since he thinks he has seen an officer...). The harmonic context then becomes very unstable, dissonant, with an increasingly chaotic singing line.<
In my mind, if the woman had the last word, I have the impression in any case that it went really wrong... ("bruler la cervelle", In the end, means "pull in the head" Which suggests that something irremediable may happen after the wife's ultimate answer)... (In any case, that's what I wanted to make you feel in this dialogue, which in my opinion is not trivial).
It is not uncommon, in the German Lied or the French Melodie (or even the American or English "Song") to have male or female characters indifferently sung by the same "narrator" (and even sometimes animals (or even objects!)... This must be seen a bit like a declamation of poetry, more so than as an opera scene.
That said, I would have loved to summon a colleague to register the wife"s Answers, and I know that it would have been a much more readable approach for the listener, which is a quite right observation on your part!
In any case, a big thank you for these relevant observations.
