These events may have brought Sibelius to a point of crisis, forcing him to choose between changing his style to fit with the radical changes in tonality and rhythmic language prevalent among younger composers around 1910, or continuing to develop the musical language he felt familiar with. The Finnish conductor and Sibelius specialist Hannu Lintu, in discussing Symphony No. 5 on television in 2018, said that Sibelius seems to have made a definite choice, a year or two after his previous symphony, to stay within the frames of harmonic language of late-19th-century romanticism; instead he would innovate in the realms of macrostructure and instrumental colouring.
