So just how does that result in the timeless art of music?Though the swaying chirp of a tiny Hawaiian koa-wood ukulele strum and the deep, purring baritone of a contrabass may seem worlds apart, they are united by the same basic rules of physics. As a musician manipulates a string, whether by plucking it with a pick or brushing it with a bow, it vibrates at a specific frequency, creating a small, almost indiscernible sound. Within the delicately constructed body of the instrument, however, the sound resonates and amplifies, emerging as the full, sonorous timbre of a dad noodling on his old banjo in front of your friends. The frequency at which a string vibrates depends upon its tightness and length. When a musician presses down on a string, it becomes shorter, resulting in a higher frequency (or pitch). In this way, a guitarist can strum an almost infinite combination of notes and chords by controlling the given pitch of only six strings.Despite the common underlying physics, a variety of factors help to create such a diverse range of sounds among stringed instruments. When playing a fiddle, for instance, the bow simply glides across the strings, resulting in a fluid, even tone. A banjo, on the other hand, has a large round body with a resonating drumhead that creates its characteristic twang. Even the piano, though not technically a stringed instrument, operates on the same principles: tiny hammers inside the body strike individual strings, each carefully tuned to a specific pitch, producing percussive, dynamic notes among several octaves. Still, the differences between any two instruments are subtle, and even with modern tools, few
