DISCO BEATS are basically rock beats with emphasis being placed on the hi-hat playing eighth or sixteenth notes. Open the hi-hat with your foot on the "+" section of the count (off beat) and close it on the number section of the count (on the beat). As the hi-hat is opening it is hit with the stick. This is indicated by the o placed above the hi-hat.
Now by only playing the hi-hat on the "+" section of the count you can vary the disco rhythm accenting the offbeat even further. Although the following exercises are played with an open hi-hat (off the beat), it may be beneficial to first practice them with a closed hi-hat.
