Syncopation is nothing more than changing the rhythm of the chords being played. The beat stays the same, but how u play the chords change. Here is an example:
Regular Way
Key C LH/RH 4/4 time count in [ ]
[1, 2] E / Bb-Eb-G
[3, 4] F / A-D-F
[1, 2] D / Gb-A-C-Eb
[3, 4] G / F-A-C
[1, 2, 3, 4] C / E-G-C
Syncopated Rhythm Way
Key C LH/RH 4/4 time count in [ ]
[1] E / Bb-Eb-G
[2, 3, 4] F / A-D-F
[1] D / Gb-A-C-Eb
[2, 3, 4] G / F-A-C
[1, 2, 3, 4] C / E-G-C
You see the difference? In the first one the chords are being played straight thru with each chord getting equal beats. But, in the second one every other chord gets a beat longer than the one before it. That's how u use syncopation, you change how u play certain chords to give you interesting sounds. You have to really know what your doing with rhythm and time count in order to understand sycopation.
Why don't you post some stuff u play w/time counts so we can better assist you.
