The music critic Colin Mason described Bush's music thus:His range is wide, the quality of his music consistently excellent. He has the intellectual concentration of Tippett, the easy command and expansiveness of Walton, the nervous intensity of Rawsthorne, the serene leisureliness of Rubbra ... He is surpassed only in melody, as are the others, by Walton, but not even by him in harmonic richness, nor by Tippett in contrapuntal originality and the expressive power of rather austere musical thought, nor by Rawsthorne in concise, compelling utterance and telling invention, nor by Rubbra in handling large forms well.
