Item #: SCP-628
Object Class: Euclid
Laconic Containment Procedures: Don't let anyone near SCP-628 without permission. Don't let anyone but D-class near it without earthquake detectors and really good earplugs. Anything you build near it should be able to stand up to an earthquake. If the wind suddenly picks up near it, everyone should go to a soundproof room. A Mobile Task Force of plant experts will help take care of it and keep it healthy.
Laconic Description: SCP-628 is a group of hollow, leafless sycamore trees that are all connected underground by big hollow roots. When the wind blows over the broken ends of their trunks, it mimics the sound of a pipe organ pitched extremely low. Sometimes they play real-world classical music, but sometimes they make up their own songs.
When anyone tries to chop a part of SCP-628, it plays Bach music so loud that it injures people and causes an earthquake.
Additional Context: The author came up with the idea for SCP-628 after seeing a big broken-off tree. Someone had put a metal cap over the broken end, which made it look a little like a clarinet.
