Counterpoint Lession 7: Free counterpoint

Free counterpoint

Part I - Free Counterpoint
Free counterpoint combines all the other species into one.  In this type of counterpoint, one is able to have note-against-note, two against one, three against one, and four against one.  Although not as common, it is possible to have two against three, and three against four.

Notice that there exists 3:1 and 2:3, as well as 2:1 in this example. 
Part II - Simple two-reprise Form
Also known as binary form, This most commonly exists as simple dance movements, Such as gigues1 or sarabandes2.  Two-reprise pieces most commonly exist in sixteen, or twenty-four measures, The layout of the piece often looks like this:

||:8 measures:||:8 measures:||    and       ||:8 measures:||:16 measures:||
       Tonic                     Dominant                                             Tonic                      Dominant
Even though the piece modulates for the second part, the overall feel of the piece does not shift (i.e. major/minor, tempo, etc.)  Although the general feel of a piece does not change, it is  normal to see a piece change tonality between the two sections.To facilitate this shift, the last measure of each section often tonicizes to the new tonic of the next section.  Like this:

Major:                                                       minor:
||:I             V(iii):||        ||:i              v(V, or III):||

An example of the simple two-reprise form can be found in Bach's Minuet in d minor, BVW Anh.132
 
Notice that in the second part, the tonality shifts in the second part of the piece.
