Why the damper stops the note

A felt damper rests on the string and stops it from ringing once the key is released.

From the opening

The damper is a felt pad that sits on the string and keeps it quiet until the key is played. Lifting the damper lets the string ring, and dropping the damper back onto the wire kills the vibration by friction. The opening covers felt rests on the string, the key lifts the damper, and the sustain pedal lifts all.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
