K.16, Symphony N.1, Molto Allegro - I like the soft part, immediately following the introduction of the rude-sounding theme.  It sounds sweet, pretty.  The minor part following the second introduction of the main theme (the repetition of the main theme) is not bad either.  I think there was some development following the minor theme (before the reintroduction, for the third time, of the main theme), but it failed to strike much at me.
K.16, Symphony N.1, Andante - This is prettier or at least stranger than the previous.  The movement is Andante, walking, but the theme is cautious and swelling.  When the theme goes quite quiet, the harpsichord accompaniment is pretty.  It has its own voice.  This portion of the work ends softly.
K.16, Symphony N.1, Presto - In the last few pieces, I have often found the scaling downward parts the most interesting.  Here, I think this is also the case, perhaps because the scale creates some dissonance with the horn, which holds one note.
