Percussion Ambient · Pelog 7 Tones KF (Sundanese, Bandung — ref. 451.09 Hz)

Second piece in a daily series exploring percussion as lead voice, not rhythm section. A four-phase ceremonial arc — Invocation, Emergence, Transfiguration, Return — built through both harmony and material: earth and skin tones open the ritual, air textures join as it widens, metal and pitched percussion peak, then everything dissolves to a single held tone.

Tuned to Pelog 7 Tones KF, centered on Tugu (A).
