Ngày Xưa Trên Sân Trường
Nostalgic V-pop ballad with gentle piano and fingerpicked acoustic guitar, male vocals. Verses stay intimate and close-mic, light pads tucked behind. Chorus lifts with warm string layer, soft tom fills, and subtle backing “ahh” harmonies. Final chorus adds a key change and extra ad-libs, ending on a held vocal over a fading piano chord.
