The E's and Ah's of Drum Fills
Putting a strong emphasis on the syncopated strokes (i.e. the “E” and “Ah”) in a drum fill gives the fill a … well, more syncopated feel.
Beyond that, it makes the groove sound more complex and difficult than it actually is. That reason alone, however, shouldn’t be why you choose to play a syncopated fill. Syncopation feels energetic, funky and naturally makes people want to move. If this is the feel you need to present in a song, try some “E’s” and “Ah’s.”
