Most musicologists agreed with this analysis until Hepokoski's 1993 text "Sibelius: Symphony No. 5" offered an altogether different interpretation. He argues that the piece can only be analysed in terms of what he has called "rotational form". He maintains the same divisional sections of the movement – double exposition, Scherzo, and recapitulation – but uses new vocabulary for its analysis. Hepokoski argues that Sibelius allows the material to determine form in many of his works, developing by the necessity of the music and not by an 18th- or 19th-century template; in the Fifth Symphony a circular rotation or strophe passes through sections of material, further developing it with each rotation. Through this analysis Hepokoski maintains the general location of sectional changes described by the earlier musicologists and agrees that the movement can roughly be analysed in sonata form.
