veneer
A thin sheet of wood glued to various cabinet parts. The stronger, but plainer-looking core wood is invariably first covered with "cross banding" glued at right angles to its grain, and then the cross banding is covered with fancy veneer with the grain running parallel to the core. This sandwich greatly strengthens a cabinet against cracking and warping. Marquetry consists of small pieces of veneer of various grain patterns and colors inlaid flush into the surface of the surrounding veneer to create various designs, borders, etc.

vibrato
A rapid, repetitive change in pitch used by musicians for imparting more warmth or emotion to music. A vibrato effect is achieved in the Mills Violano-Virtuoso by shaking the tail piece, and in the Hupfeld Phonoliszt-Violina by acting on the string tension. In organs, the effect is achieved by shaking the wind supply. See also tremolo.
