As all here have stated, great book and so much can be learned from it. When learning such techniques it is all ways good to start at the basics. if you understand that with in a beat there are 3 ways to deliver it, before it, on it and after it. Understanding this and using it in time signatures and rythmns will give you the feelings desire and hear. for example we all know 4/4 is:
1-2-3-4-2-2-3-4-3-2-3-4-4-2-3-4 or beat beat beat beat beat beat beat beat beat beat beat beat beat beat beat beat
as an example of 4 bars of 4/4 which is 16 beats. If we use the word beat as a way of spliting up our beat into the 3 ways mentioned of before, on and after, then on the beat would look like this if we use the symbol of ^ to show where the beat or accent is:
be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at be^at
with the accent or beat played firmly in the middle of beat.
If we play before the beat it would look like this:
b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat b^eat
with the accent or beat played just before or ahead of the beat as the name suggests.
And if we play after the beat it would look like his:
bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t bea^t
with the accent or beat now played later or after the beat as the name suggests.
The blending of some or all of the techniques will give you basic variation or syncopation on a straight simple rythmn or beat, making it seem more complex than it is for example.
be^at be^at b^eat b^eat be^at be^at b^eat be^at b^eat b^eat be^at b^eat be^at b^eat bea^t bea^t
Whether these are true notes, muted, or ghost notes will add to the variation and syncopation or what you play. Country, blues and folk music have great examples of playing before, on, and behind the beat which are quite easy to follow when you have the idea down.
Then you can move to spliting the beat a bit more adventuresly as in
b^ea^t b^e^at^ be^at bea^t^ b^e^at be^at and so on
by spliting the beat within itself with muted, ghost and real notes, with in triplet and so fourth.
Hope this visual representation helps rather than confuse when you come to play them. LOL
