Akira Ifukube
For Godzilla's roar, the recording artists initially used multiple roars from various large animals. These recordings ended up sounding like their animal counterparts and went unused. The film's composer Akira Ifukube decided to create the roar with instruments. Ifukube rubbed a leather glove through the loosened lower strings of a contrabass and altered the pitch and speed of the recording until the final roar was conceived.
