A lot of my students have trouble playing piano with both of their hands.
The trick is to slow down the music to the point that your hands are playing together – even if its EXTREMELY slow and boring. Too many people try to play the song up to tempo, and then complain that they can’t have both their hands play together.
You have to learn to walk before you run. It could take months to get the syncopation down, but when you do then you’re building a foundation. Then simply build on top of that foundation. Turn your metronome off, and just get used to sightreading and, then slowly build yourself up. After you get the comfort zone, turn the metronome on at a slow speed, and over time increase the speeds.
Once you learn it though, you’re good forever – so do it correct the first time :)
