17th century 4 part voice writing for ap music theory test

[stiefel]

Does anyone know of a good, informative book, website, or some other source that teaches about traditional methods of 4 part voice writing? (ex: soprano, alto, tenor, bass)

The reason I'm looking for a book is because I'm taking the Ap music theory test soon and want some help with this.  Things I must do include write bass lines given a soprano line and figured bass notation.  Or, write tenor and alto lines given bass and soprano.

Are you saying that you have not studied this yet, but will be writing an exam on it soon?

There is a book I own called gradus ad parnassum "the art of counterpoint" translated from latin to english by alfred mann. It is a fairly easy to understand book talking about harmonising 2, 3 and 4 voicings and is in a fairly understandable format. Haydn and Mozart used this book extensively and although it only really focus's on counterpoint many things can be applied elsewhere. Search for "the art of counterpoint" on amazon and you will find it easily.
