Slipped

The book slipped from his lap and onto the floor.

He slipped and used a curse word in front of his grandmother.

The music slipped in volume as she turned down the radio.

The melody slipped into a slower tempo for the final verse of the song.

The singer slipped and forgot the lyrics to the song.

The guitarist slipped the pick from his fingers and it flew into the audience.

The building's safety standards have slipped over the years due to lack of maintenance.

The singer's voice slipped during the concert due to a sore throat.

I slipped up and forgot to send the important email.

He slipped his backpack off his shoulder and onto the ground.
