The metre is basically quadruple time (4), with some and bars inserted. Rhythm is relatively free, sometimes to the extent that pulse is disguised, e.g. the introduction with its mix of dotted rhythm, tied notes, triplets, syncopations and long sustained notes. Elsewhere, notice the lengthening of note-values at the ends of phrases (e.g. bar 8 - see example below), leading to a change of time signature. Triplet quavers in piano accompaniment (bar 9), Quintuplets (e.g. cello in bar 12), Septuplets (e.g. cello in bar 45)
