A chord is a combination of three or more notes of differing scale degree. You can play the notes at the same time or arpeggiate them, which means playing the notes in sequence.

Arpeggios are essentially a way of playing a chord. Mind you, people generally use the word "chord" to mean the notes are played at the same time.

Playing two or more notes at the same time creates harmony... usually ;)
