There is no specified number of beats the notes must add up to in a given bar of music true or false?​

False. Usually in music there is a time signature at the beginning of the piece, telling you how many beats should be in each measure and therefore how many should be in the bar.

False

Explanation:

Now I'm not an expert, but i play classical and i see this all the time. you have a measure that's full of notes then you get to a soft part that has a bunch of rests, now it wouldn't make sense if this was true because then the composer wouldn't be able to use that piece.
