The trilogy is indeed complete. As of last night the writing had stopped. My last bit of dissatisfaction with certain lines led to some final rewrites, and Mikaela and I worked out what was lacking in the melody of the first song, so I can confidently say that music and lyrics are complete for all three songs. Now I just need to practice between now and Saturday.
Next Tuesday is the Feast of St. Cecilia, so M's party is Saturday. If Cecilia is the Christian version of the Muses, I appreciate her help with our three songs in three barbarian tongues. :-)
