Stephen Heller: Op. 47 No. 25 in A Major (25 Studies for Rhythm and Expression)

Targeted at Intermediate players (intermediate study curriculum (RCM Level 5–6)), this score presents rewarding interpretive and tactile hurdles. Attention should center on managing two-part hand coordination and synchronizing pedal changes with harmonic shifts. Accompaniment passages containing transparent two-part polyphony and classical Alberti motion require subdued dynamics to spotlight the melody. Mechanically, coordinate pedal depressions immediately after finger strikes to keep harmonies articulate. Practice Focus: drill awkward chord shifts at 60% tempo, ensuring fingers assume target hand shapes before descending.

In 4/4 (simple quadruple meter), rhythmic continuity is shaped by an authoritative quadruple framework where downbeat accents anchor the overarching phrase architecture. The reference performance speed is ♩ = 139 BPM (*Allegro vivace*), yielding a dynamic with vigorous kinetic momentum tempo profile. From a phrasing standpoint, channel energy through the middle beats toward subsequent downbeats to preserve continuous phrasing arcs.

The foundational pitch center is A Major (three sharps (F♯, C♯, G♯)). Here, A serves as the primary resting point, while modulations into F-sharp Minor and dominant tensions in E Major shape the emotional contour. Harmonically, the progression A → E → F#m → D cycles smoothly through harmonic steps (F#m, D) back toward the tonic. From a tactile perspective, navigating this key delivers a brilliant upper tessitura demanding attentive thumb passage beneath fingers two and three during arpeggios.
