of Part II, by deciding
whether it leads directly into Part III, or comes to a conclusion
somewhat earlier, to make room for a Retransition; then the end of Part
III, by deciding whether a codetta or coda has been added. The
extremities of the three Parts being thus determined, there will be no
difficulty in defining the _form_ of each. Very particular attention
must be devoted to _the comparison of Part III with Part I_, in order
to discover, and accurately define, the difference between them,--in
form, in extent, in melodic formation, or in technical treatment.

_Menuetto_ and the _Trio_. Op. 2, No. 2, third movement,--both
_Scherzo_ and _Trio_. Same sonata, last movement, first 16 measures
(Parts II and III consist of a single phrase each; therefore the whole
