Air on the G String Wilhelmj arranged the second movement of Bach's third Orchestral Suite for violin and an accompaniment of strings, piano or organ (harmonium). On the score he had printed (on the G string) above the stave for the solo violin, which gave the arrangement its nickname. In Wilhelmj's version the piece is transposed down from its original key (D major) to C major. Then the part of the first violins is transposed down a further octave and given to a solo violin that can play the entire melody on its lowest string, the G string. The dynamic markings added by Wilhelmj are
String (music) core of the string. Bowed instrument strings, such as for the violin or cello, are usually described by tension rather than gauge. Fretted instruments (guitar, banjo, etc.) strings are usually described by "gauge"—the diameter of the string. The tone of a string depends partly on weight, and, therefore, on its diameter—its gauge. Usually, string manufacturers that don't describe strings by tension list string diameter in thousandths of an inch (0.001 in = 0.0254 mm). The larger the diameter, the heavier the string. Heavier strings require more tension for the same pitch and are, as a consequence, harder to press down
