Air on the G String material of the other parts of Bach's piece, although occasionally versions that stay more in line with Bach's original can go by the same name. Air on the G String "Air on the G String" is August Wilhelmj's arrangement of the second movement in Johann Sebastian Bach's Orchestral Suite No. 3 in D major, BWV 1068. The arrangement differs from the original in that the part of the first violins is transposed down so that it can be played entirely on a violin's lowest string, "i.e.", the G string. It is played by a single violin (instead of by the

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
