Synchronisms are events happening at the same time or in a way that matches.
Synchronisms can be interesting because they show how things can happen together.
Examples:
The clapping and the music were perfect synchronisms.
The dance moves were in perfect synchronisms with the music.
The birds flying and the sun setting were beautiful synchronisms.
The dogs barking and the babies crying were not perfect synchronisms.
The cars honking and the people shouting were loud synchronisms.
The flowers blooming and the bees buzzing were lovely synchronisms.
