What I'm talking about is in Taiko and Mania, when you hit an input, you'll receive a sound, even if there's no notes on the screen. I find this fun, especially during breaks I can tap various rhythms to the beat. In short paced sections sometimes I'll do the same. For example, in taiko, if there's a row of half notes incoming, I might tap in the rhythm of quarter notes.
