Chuông Lớp Học

Educational ambient pop-instrumental with a light marimba pulse, soft ukulele plucks, brushed percussion, and friendly bell motifs; intro opens with a clear school-bell cue, verse sections stay minimal for teaching narration, activity-change moments add playful claps and hand-drum lifts, reward cues brighten with chimes and a short uplifting synth rise. Clean, warm, classroom-friendly mix with a bright center and gentle stereo sparkle.
