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 instrument string with higher mass per unit length produces the lower pitch. The length of the string from nut to bridge on bowed or plucked instruments ultimately determines the distance between different notes on the instrument. For example, a double bass with its low range needs a scale length of around , whilst a violin scale is only about . On the shorter scale of the violin, the left hand may easily reach a range of slightly more than two octaves without shifting position, while on the bass' longer scale, a single octave or a ninth is reachable in lower positions.
