Cooke refers to "a new granite-like hardness of orchestration" in the middle-period symphonies, while the songs have lost most of their folk character, and cease to fertilise the symphonies as explicitly as before.
Cooke refírese a «unha nova orquestración dura coma o granito» nas sinfonías do período medio, mentres que as cancións perderon a maior parte do seu carácter folclórico e deixou abonar as sinfonías tan explicitamente como antes.
