Summary:A piano includes an underlever assembly having an underlever arm (17) and an underlever support joining the underlever arm (17) to a string damper (11). The underlever arm (17) is mounted to move between an at-rest position and a second position. A latch (106) is mounted to a latch mount (165) for movement between non-latching and latching positions. In latching position, the latch (106) engages a latch surface (97) of the underlever support to maintain the string damper (11) spaced from a corresponding piano string (12). A stop mounted to the latch mount limits movement of the underlever arm toward its second position. A method for controlling a piano string damper (11) includes contacting the underlever arm (17) with the latch (106) to maintain the string damper (11) spaced from the string (12), and contacting the underlever arm with the stop to limit movement of the underlever arm.
