A stringed musical instrument having multiple bridge-soundboard units, each unit substantially acoustically independent from other bridge-soundboard units. Said bridge soundboard units are coupled to a set of strings such that a number of the strings within the set are sounded through the first bridge-soundboard unit, others are sounded through a second bridge-soundboard unit, and so on. The process of division of set of strings among several bridge-soundboard units allows greater ability to bear tension, greater sustain, and greater variety of tonal color by allowing a greater number and variety of soundboards.
