139, is a concerto for three instruments – violin, harp and double bass – and orchestra by Dmitri Smirnov, composed in 2003.

1 for saxophone, piano, double bass, strings and percussion in 1977[1] when he lived in Russia,[2] and the Triple Concerto No.

[3][4] The soloists were violinist Gordan Nikolitch, harpist Bryn Lewis, and double bassist Rinat Ibragimov,[3] all principal players of the LSO.

[4] The Triple Concerto is structured in three sections or movements:[4] Smirnov scored the work for the three solo instruments, and an orchestra consisting of piccolo, cor anglais, bass clarinet, percussion (3–4 players of timpani, triangle, suspended cymbal, maracas, woodblock, bongos, tom-tom, gongs, tam-tam, side drum, bass drum, glockenspiel, xylophone, bells), and strings.

[4] The three solo instruments complement each other, comparable to the voice types soprano for the violin, mezzo-soprano for the harp, and basso profundo for the double bass.
