Obelus No.4

Designed for Intermediate level pianists (intermediate benchmark (ABRSM/RCM Grade 4–6)), this piece demands clean articulation and hand balance. The chief hurdle entails projecting the cantabile soprano melody while suppressing inner accompaniment voices. Balancing broken arpeggio figures and modern pulse chords requires distinct volume separation between parts. Furthermore, coordinate pedaling with chord changes to maintain acoustic warmth. Practice Focus: practice left-hand harmonic leaps with closed eyes to develop spatial keyboard instinct.

Created by Jannuel Graceche, the composition Obelus No.4 demonstrates notable craftsmanship within the popular pop sheet music repertoire. Encompassing 64 measures over 3 engraved pages, the work is collated from accurate modern sheet transcriptions. Authority databases register this work as `mbid-838e3b93-sheetpdf` and ISWC `T-838.E3B.93-1`.

Tonal grounding is defined by C Minor, marked in the score by three flats (B♭, E♭, A♭, with B♮ raised leading tone). The music alternates stability on C with expressive harmonic excursions toward E-flat Major and its parallel relation, C Major. Harmonically, the progression Cm → Dm → G → C → F → E7 cycles smoothly through harmonic steps (F, E7) back toward the tonic. At the keyboard, C Minor provides an intense heroic key signature that commands deep shoulder weight on dramatic downbeat chords.

The temporal design is written in 4/4 (simple quadruple meter), establishing a balanced metric groundwork providing grounded stability with primary weight on beat one and secondary stress on beat three. The indicated tempo mark of ♩ = 135 BPM (*Allegro*) suggests an atmosphere that is energetic, driving, and propelled. Interpretively, channel energy through the middle beats toward subsequent downbeats to preserve continuous phrasing arcs.
