Double bass concerto

A double bass concerto is a notated musical composition, usually in three parts or movements (see concerto), for a solo double bass accompanied by an orchestra. Bass concertos typically require an advanced level of technique, as they often use very high-register passages, harmonics, challenging scale and arpeggio lines and difficult bowing techniques. Music students typically play bass concerti with the orchestral part played by a pianist who reads from an orchestral reduction (the orchestra parts arranged for piano).
