At night, the pit-a-pats of rain on the roof lulled her to sleep.

When he smiles at her from across the classroom, her heart pit-a-pats.

When she heard footsteps behind her, her heart pit-a-patted until the sound faded.

My heart was pit-a-patting as I waited for the interview to begin.

Rain began to pit-a-pat on the tin roof, lulling me to sleep.

Lying awake, I listened to the pit-a-pat of rain on the window until I drifted off.

The rain fell pit-a-pat on the tin roof throughout the night.
