Warning: Forehead Tapping is a highly addictive habit. Once you start, you'll be tapping your forehead for hours.
For best results, tap in sync with your favorite tunes. The beat of the music will guide your taps, much like a metronome on steroids.
For the most advanced practitioners, there's even Forehead Tapping in 5/4 time. Don't worry if your brain hurts, it's just the rhythm.
