>"As he had done in Hiroshima and in Godzilla, Ifukube used the piano - or in the case of Rodan, two pianos and a timpani - to craft a musical "special effect." The effect in question is heard during one of the film's many earthquakes. In "scoring" the temblor, Ifukube requires that the timpanist perform several consecutive glissandi on his drum with the pedal down. The pianos, with their pedals down as well, are manipulated directly on the strings: The player of "Piano I " carries out a series of up and down glissandi on the harp with a rubber stick while the the player of "Piano II" does the same on his instrument, but with a wooden stick. The final effect is one of a surreal, disquieting rumble."
