[The opening remains harmonically ambiguous over G before the radiant clarity of C major is revealed.] [The harmonic foundation alternates primarily between C and F while expressive colors of G minor, D minor, G major and A-flat major appear naturally throughout.] [The full string ensemble maintains a continuous flowing legato eighth-note ostinato grouped in repeating threes throughout the entire movement.] [The ostinato never stops.] [Momentum comes from strings, choir and harmony, never percussion.] [The choir is the principal instrument.] [The cathedral pipe organ is an equal musical partner.] [Opening Organ Registration: Swell Strings 8’, Celeste 8’, Stopped Flute 8’, Bourdon 16’ Pedal.] [Aurora.] [Organ solo.] [The organ quietly introduces the principal theme.] [Choir I.] Deus adest! [Choir II.] In aeternum! [Both choirs.] Deus nobiscum. [Extended melisma on “aeternum.”] [Change Organ Registration.] [Great Principal Chorus: Principal 8’, Octave 4’, Fifteenth 2’, Swell coupled to Great, Trumpet 8’.] [The revelation of radiant C major.] [Ascensio.] [Choirs begin weaving independent lines.] Semper nobiscum. Deus adest. In aeternum. Semper… …nobiscum… [Organ answers the choir.] [Timpani reinforce only structural arrivals.] [Maintain transparent orchestration.] [Amplitudo.] [Professional SATB divisi.] [Independent contrapuntal vocal lines.] [The recurring A-flat major harmonic bloom returns before resolving naturally.] [Full strings.] [Radiant brass reinforce harmony.] Deus adest! In aeternum! Semper nobiscum. [Extended joyful melisma on “aeternum.”] Deus adest. [Final Organ Registration.] [Full Organ: Principal Chorus, Mixtures, Trompette 8’, Clairon 4’, Posaune 16’ Pedal, Full Swell with reeds.] [Gaudium.] [The entire cathedral sings with one voice.] [Choir and organ now speak together.] [Everything aligns with the meter.] [The orchestra broadens without becoming denser.] [Final radiant harmonic bloom before returning home.] Deus nobiscum! Deus adest! In aeternum! Amen… [Final organ solo.] [Allow the final full-organ C-major sonority to resonate naturally throughout the cathedral before fading into silence.] AMEN.........!
