Doug, forgive my ignorance - I know pentatonic but pentametric? Music in
five meters? - even Stravinsky..... And, pray tell, what are Alexandrines?
Perhaps a Roman tea biscuit.....
And as to choral compositions wherein inspiration, etc., I would find that
Elgar's "Dream of Gerontius" fits your qualifications superbly for my
taste - but, then.....
My dots have gotten the best of me.
Best wishes,
Phil
