Regina coeli, T 112

Framed in C Major, the score establishes C through a key signature featuring zero sharps and zero flats. Harmonic variety is enriched through dialogue with the relative minor/major (A Minor) alongside strong cadential support from G Major. The chordal vocabulary centers upon stable tonic statements alternating with G Major pivots. Pianistically, the key produces a natural diatonic surface where the absence of black keys demands disciplined hand stability and balanced posture.

Metric propulsion relies on 4/4 (simple quadruple meter), giving the piece a steady common-time pulse providing natural rhythmic symmetry across four quarter-note subdivisions. Set to a metronome speed of ♩ = 88 BPM (*Andantino*), the overall character feels moderately flowing with clear articulation. Pianists should ensure that they avoid pounding downbeats mechanically; keep the line buoyant through intermediate pulses.

Regina coeli, T 112 highlights William Byrd's refined handling of musical materials in the modern classical keyboard selections. The complete engraving encompasses 32 measures across 2 pages, verified against accurate modern sheet transcriptions. Bibliographic registers identify this title under ISWC `T-72F.9FF.6D-1` and catalog entry `mbid-72f9ff6d-pianistforum`.

Positioned within the Intermediate repertoire (intermediate study curriculum (RCM Level 5–6)), this work offers valuable training in balance and tone. Performers must concentrate on managing two-part hand coordination and synchronizing pedal changes with harmonic shifts. Navigating transparent two-part polyphony and classical Alberti motion asks for deliberate finger weight distribution. To preserve clarity, lift the damper pedal cleanly on phrase boundaries to preserve classical transparency. Preparatory Exercise: play the melody forte while ghost-tapping the accompaniment keys silently beneath the surface. Score pointer: Juilliard Practice Blueprint for Regina coeli, T 112: Master hands-separate voice isolation at 65% tempo. Focus on balanced hand independence, singing tone proj.
