This tone row does not sound as random as many tone rows are because parts of it sound quite tonal. This is because the first three notes are a G minor triad; notes three to five are a D major triad; notes five to seven are an A minor triad; notes seven to nine are an E major triad; and the last four notes together make up part of a whole tone scale. The first notes of each group of triads together form G, D, A and E, which are the open strings of the violin. The opening of the concerto makes this very obvious.
