| Much like the metal string used for most orchestral string instruments. Though nylon and cat gut strings are somewhat elastic they should not be considered elastic as they are tuned to set pitches in such a manner elasticity is minimized and not a feature of the way they generate sound. | Much like the metal string used for most orchestral string instruments.
