"An unstable tone combination is a dissonance; its tension demands an onward motion to a stable chord. Thus dissonant chords are 'active'; traditionally they have been considered harsh and have expressed pain, grief, and conflict."

It's very hard to give a precise definition of dissonance. I guess to put it simply, dissonance is a combination of notes/pitches that sound unstable.
