possibly was even aware of. This hidden structure is furthermore confirmed within the analysis of the entire exposition, which revealed a correspondence of this second segment to the $6 4$ -meter in figure 58.

Metric weight of figure 65 interpreted as $64$

The metric weight of the isolated third segment of the exposition in figure 67 is characterized by great metric weights on the fourth beats of the measures in the first half of the picture, similar to the results of the isolated analysis of the first segment. Interestingly in the second half of the picture again a periodicity can be stated similar to the isolated analysis of the second segment: every second beat gets a greater metric weight.

4.2 Third movement

The third movement Poco Allegretto (time signature $38$ ) is segmented into three parts of different key signatures: measures 1-53 in E sharp Major, measures 54-98 in A sharp Major, the last part in E sharp Major repeats the opening theme. Here we want to discuss the two segments in E sharp Major (for the discussion of the middle part see Fleischer, 2003, p. 115).
