Abstract

Contemporary Indonesian choral compositions increasingly incorporate traditional musical idioms such as gamelan and kecak into modern SATB frameworks. This study explores how selected choral works reinterpret these idioms by prioritizing rhythm, vocal texture, and articulation over conventional harmonic progressions. The objective is to understand how rhythm can function as a primary harmonic agent in a cappella settings. The methodology involves analytical comparison of three compositions Janger (Budi Susanto Yohanes), Cikala le Pong Pong, and Hela Rotan (both by Ken Steven). Through transcription, rhythm mapping, and texture classification, this study reveals the strategic layering of rhythmic motifs, percussive vocal effects, and responsorial structures across SATB and divisi settings. Results show that Janger employs interlocking vocal ostinati and contrasting articulations to emulate gamelan textures. Cikala le Pong Pong uses body percussion, chest voice, and glissandi to generate dissonant harmonic fields. Hela Rotan adapts Eastern Indonesian rhythmic idioms through responsorial phrasing, leading to emergent polyphonic verticalities. These techniques collectively redefine choral harmony through rhythmic density and vocal layering. Discussion highlights how these works negotiate cultural fidelity and artistic innovation. They challenge Western centric harmonic paradigms by elevating rhythm and texture as compositional pillars. Such approaches not only contribute to decolonizing harmonic theory but also enrich global choral repertoires through culturally grounded, structurally inventive music.

Abstract

This study investigates the impact of singer body movement on ensemble coordination and perceived expressivity in choral performance. Grounded in theories of embodied music cognition and entrainment, the research explores how varying degrees of movement no movement, slight sway, and full body sway affect acoustic precision, synchrony, and audience evaluation. Using a within subject factorial design, 24 university level choir members performed under each movement condition. Data were collected through multi microphone recordings, OpenPose based motion tracking, and blind evaluations by expert and non expert listeners. Acoustic measures included pitch deviation, LTAS, and SPL; movement metrics captured sway amplitude and synchrony; perceptual ratings addressed expressiveness, articulation, and timing. Results indicated that slight sway consistently produced superior outcomes across all domains. Pitch deviation was lowest and movement synchrony highest under this condition. Perceptual ratings were significantly higher in slight sway than in either no movement or full body sway. Excessive movement increased pitch instability and disrupted blend, while also producing inconsistent synchronization. These findings highlight the functional role of calibrated movement in choral performance. Incorporating slight, synchronized motion can enhance ensemble cohesion and elevate audience experience without compromising acoustic integrity. The study offers empirical support for movement integrated pedagogies and suggests broader applications across ensemble types and performance genres.
