The unaccented part of a bar, as opposed to the strong beat. In 4/4 time beats two and four are weak beats. Older German-language textbooks also call it the “bad” part of the bar.

A weak beat is a part of a bar that has less weight in the metre than the strong one. The first beat carries the greatest weight in the bar, the other beats stand back behind it. In 4/4 time two and four are weak, three is half-strong. In 3/4 time two and three are weak.
An upbeat on a weak beat
The piece begins with an upbeat: the first note falls on beat four, so on a weak beat. The marked notes are those on weak beats: the upbeat itself, the two and the four in the first bar and the four in the second bar (the upbeat counts as bar 0). The final bar has only three beats: upbeat and final bar together make one full bar.
On the old name
Older German textbooks also call the weak beat the “bad” part of the bar. “Bad” has nothing to do with quality there but means “plain” or “slight”. The word belongs to an older teaching of metre in which one spoke of the “good” (strong) and “bad” (weak) part of the bar. Today one mostly speaks of strong and weak.
Why weak beats matter
A bar lives from the gradient between strong and weak. Weak beats lead on to the next one. This becomes especially clear with the upbeat: it stands on weak beats and pulls the melody towards the strong one. Many songs begin like that. Weak beats are also the place for ornaments, passing notes and runs that do not disturb the pulse.
When weak beats are stressed
If a weak beat is stressed deliberately, a counter-accent arises. That is the core of syncopation and of the offbeat, which places the stroke between the beats. With the backbeat in pop and rock the accent lies on two and four, so on the weak beats of 4/4 time.
