V54 — NOW INCLUDED IN FRUIT CATCH
Vivaldi – Spring: I. Allegro (La Primavera, Op. 8 No. 1, RV 269)
RhyFlow synthesized marimba/percussion adapted excerpt, not the full movement.

SPRING IN THE SOUND GARDEN — RHYFLOW AUDIO PREVIEW 1
15 October 2026

A new synthesized marimba/percussion arrangement of the opening of Antonio Vivaldi's Spring, RV 269, first movement. This is an adapted excerpt, not the full movement or an orchestral performance. No sampled performance or commercial sound-module sounds were used.

LISTEN FIRST
Spring_Garden_Preview.wav: standalone listening version with an opening pickup and gentle ending, approximately 36 seconds.
Spring_Garden_Loop.wav: 16-bar, 112 BPM, E major, 4/4 loop master, approximately 34.286 seconds. Tails wrap into the start. The final eighth-note E acts as the pickup to the next cycle.
Spring_Garden_Loop.m4a: smaller same-loop delivery candidate.
Spring_Garden_Loop_Soft.m4a: same candidate at -10 dB.
The loop files and standalone preview deliberately have different endings.

ARRANGEMENT
Marimba melody, soft wooden-bar accompaniment, rounded bass, light hand drum, shaker and woodblock. Opening melody/rhythms checked against the listed score; voicing, dynamics, simplified cadence and turnaround are adaptations. Source trills/ornaments are simplified. Synthesized instruments do not reproduce real recorded marimba timbre exactly.

No game files were changed and no deployment was made. Do not replace the live track before listening. Native/AAC loop seams, loudness against speech and first play still need a real iPhone/iPad check. File-boundary continuity alone does not verify a browser's audio looping behaviour. The Soft mix is a relative gain choice, not a calibrated sound-pressure guarantee.
