Upon arriving in Hollywood in February 1936, Fischinger was given an office at Paramount Studios, German-speaking secretaries, an English tutor, and a weekly salary of $250.($4400 in 2017 dollars, adjusted for inflation). He and Elfriede socialized with the émigré community. As he waited for his assignment to begin, Fischinger sketched and painted. He prepared a film which was originally named Radio Dynamics, but known today as Allegretto, tightly synchronized to Ralph Rainger's tune "Radio Dynamics". This short film was planned for inclusion in the feature film The Big Broadcast of 1937 (1936). However, Paramount only planned to release in black-and-white film, which was not communicated to Fischinger when he began his work. Paramount would not allow even a test in color of Fischinger's film. Fischinger requested to be let out of his contract and left Paramount. Several years later, with the help of Hilla von Rebay and a grant from the Museum of Non-Objective Painting (later The Guggenheim), he was able to buy the film back from Paramount. Fischinger then redid and re-painted the cels and made a color version to his satisfaction which he then called Allegretto. According to biographer William Moritz, this became one of the most-screened and successful films of visual music's history, and one of Fischinger's most popular films.
