Mark Guiliana takes practicing a little bit further. Watch how he improves his accuracy for playing time.

The video starts with the regular exercise of eight notes to triplets to sixteenth notes.

Then, he takes it to another level by playing only the first two notes of each beat.
This derived from the idea that when every second note of each rate is played accurate, the rest of the notes will be better in place as well.
