Jingling keys followed by a drop

You're presented with the distinct, resonating sound of keys jingling, producing a melody of metallic notes. The sound is reminiscent of a keyring, holding multiple keys, being shaken lightly. The jangling noise they make is clear and sharp, ringing out in the air with each movement. Almost abruptly, this symphony of jingles is broken by a singular, pronounced sound of a drop. The metallic echo that follows suggests the keys have been dropped onto a hard surface. The sequence of sounds paints a vivid picture of a keyring being handled and then accidentally dropped.
