DESCRIPTION:Some stringed instruments\, such as the piano\, have multiple 
 strings associated with each note.  This has a consequence for the sound 
 which is not immediately obvious: coupling between the strings can produce
  a decay profile for the note which starts steep\, but gives way to a slow
 er decay later in the note. To an extent\, a piano tuner can tailor this d
 ouble-decay profile by subtle adjustments. The talk will explore the physi
 cs behind this phenomenon\, and examine whether other stringed instruments
  would be expected to display a similar effect. A criterion based on a mea
 surement of the soundboard vibration at the string’s attachment point wi
 ll be developed\, and illustrated with data from several different stringe
 d instruments.
