With its fluent use of gimmicks, it would be easy to mock this, starting as it does with an aleatory twitter which leads on to pentatonic doodling of a kind that one improvised as a child on the black keys of the piano. Then comes the first of the tapes of the songs of the great humpback whale, recorded specially, followed by the first huge climax, very impressive except that the pentatonic melody which roars out on trombones (leading to whale-song imitations) is not distinctive enough, almost banal, punctuated by glockenspiel.[7]
