Description: SCP-CN-625 is a north-south arch bridge located in the Chinese portion of the Altai Mountains, 6.62 km in length. The bridge is composed of larch wood and marble. The surface of the bridge is composed of approximately 160 x 75 x 75 cm wood blocks in series. The wood is dark brown, and only one side has railings. A 12 cm gap is present between the bridge and the bridge pier; atmospheric measuring indicates that the density of the air is twice that of the surrounding area. Below the central pier are three 60.3 cm long stone slabs, which are at a 21 degree angle when the object is inactive.
At irregular intervals (3-99 min), SCP-CN-625 will activate and its body, as well as the stone slabs at the base of the central pier, will systematically move1. When the body of the bridge moves, the sound of a piano will be produced. Each wood block corresponds to a particular pitch, with the;southernmost block corresponding to the lowest note and the northernmost to the highest; the lengths of each note's reverberation corresponds the state of the stone slabs. The total pitch range is A0 to C8, matching that of a 88-key piano. Each time the object activates, it will play one or more pieces of music. In a single manifestation, multiple distinct volumes of piano notes may b eplayed if the composition calls for it.
As of this writing, all music produced by SCP-CN-625 corresponds to pieces that have been actually performed or written; not recorded pieces are from any later than the 1950s. Of note is that regardless of whether the piece is played with a piano or with more than one instrument, SCP-CN-625 will play all instruments' parts.
The Foundation discovered SCP-CN-625 on 18██/██/██, when its activation caused the deaths of ██ civilians. Up till 1970/██/██, SCP-CN-625 has activated a total of ████ times.
Addendum 1: Partial Activation Record
| Date | No. | Length | Composition | Notes |
|---|---|---|---|---|

Addendum 2: Incident: Neutralization
On1974/█/██, a magnitude XI tremor was detected in SCP-CN-625, causing it to fall over. Other than the areas hit by debris, no damage was caused by the tremors. The debris was entirely non-anomalous. Foundation investigation revealed a recording device and two tapes, which were collected.
The two tapes can only be played back by the recording device. One tape contains all music played during SCP-CN-625's activations to date2; the other contains a monologue by an unknown male voice:
This instrument can no longer keep up with modern music, whether it is the playing or the music itself. Obsolete.
But I hope I can obtain a better instrument soon.
