If you don't already know, this is an old Michael Jackson song he released in the early 90's. This version played by Alien Ant Farm is a little faster and uses all guitars. For the beginners trying this song your main obstacle will be the speed. Remember, start slow and in time then work your speed up. There's no point in trying it fast first up, you'll only practice it with mistakes.
Watch you timing, the first A5 chord is played on the 4th half beat, marked red
(1&2&3&4&). Remember, start slow then work up the speed. To get this riff sounding correct, make sure you put in the rests. Listen to the midi above and hear where the notes are cut short, those notes are rests. Listen to the midi below to hear how it sounds without rests.
The F5 at the end of the 1st bar below is sometimes refereed to as being pushed. Normally it would fall on the 2nd bar 1st beat, but in this case it is played 1/2 a beat earlier. This happens a lot in this song.
