Rodolfo Biagi (March 14, 1906 - September 24, 1969) was an Argentine Tango musician who started his musical career by playing background music for silent movies, and this was where he was first discovered by a tango band leader. As a tango pianist, he played with several orchestras. He played for the orchestra of Juan D'Arienzo from 1935 to 1938, and is often partly credited for the development of D'Arienzos rhythmic style. He later formed his own orchestra, and the special rhythmic qualities of his music is easily recognisable.
