Google it!
Dig up university sites... or start attending lectures - that's the best way to get what you need.
A bit more care when asking a question may help as well buddy.

Below is the first link that google showed me; I typed "descriptive grammar phonology":
http://wa.amu.edu.pl/wa/Courses_Descriptive_Grammar_1
Information given there will be useful.

You may as well go to MIT opencourseware.
http://ocw.mit.edu/index.htm
Go to:
Courses -> Find courses by: Topic -> Humanities -> Linguistics -> Phonology
I hope you can manage to find lecture notes afterwards, there are lots of them both at undergraduate/graduate level.

Take care:>
