These drum beats are for any ability, even complete beginner. I would however recommend learning pop and rock first. For example: 10 Basic Rock Drum Beats.
Reggae beats often have an emphasis on beat 3 of the bar. Usually this is from the bass drum or bass drum and cross stick snare. Accents are often used on the hi hats to play louder on beat 2 and 4. In more advanced reggae hi hat work, they adopt a swing feel similar to blues, jazz or country. The cross stick snare is used instead of the full snare sometimes or much of the time if the song is fairly laid back and chilled, which it usually is with reggae! Normal snare hits, or hitting the snare head and rim simultaneously are used in reggae drum fills. You can see some reggae fills in the video below.
