The pianist depresses the key
The key activates the capstan
The capstan engages the repetition
The repetition carries the jack
The jack throws the hammer
The escapement releases the hammer
The hammer strikes the string
The back check catches the hammer
The string creates the tone
The bridge carries the tone to the soundboard
The soundboard transmits the tone to the listener
The listener is moved and music is made
