The hammer moves the string, the string moves the whole bridge and soundboard, which moves all of the strings fore and aft of the bridges, which then move the bridge and soundboard, etc. It's a cycle, losing energy by displacement of air (making sound), plate flexing, rim flexing, the floor, etc. While energy does not transfer across the bridge direct to the back scale segments specific to a note played (as it does across the capo to the front duplex), it does get there in a roundabout way. > It's how well the sounding board transfers the energy to the surrounding > air and the > density of the air on any particular day that causes the plate to vibrate. Maybe, but all those vibrating strings are connected directly to the plate too. Ron N
