characteristic of the first theme associated with $4 4$ . Hence a relationship between the different thematic materials associated with the two distinct time signatures of $4 4$ and $12 -8$ is discovered in inner metric analysis.

Metric weight of wind instruments (measures 92-96)

Inner metric analyses of the different segments of this movement enlighten a characteristic of the thematic material notated as $4 4$ : greatest metric weights are situated on the second and fourth beats. A similar observation is mentioned in Frisch (1990), p. 154, regarding the piano quintet (see p. 1). Furthermore a relationship between the two distinct themes associated with the two different time signatures could be stated within the analysis of the wind instruments in measures 92-96. The lack of differentiation within the highest layer of the weight of the first segment notated as $12 -8$ furthermore corresponds to an observation in Epstein (1994) concerning the minimum of structural accents.
