remove class from parent element with jQuery?

Question

I can't figure out how to remove class from a parent element, basically I have a <audio> tag (from now on referred to as this) which is inside a div with class="playing" how can I remove this class?

tried this, but than understood that it will remove class from audio element not it's parent div:

this.removeClass("playing");

Answer 1

this.parent().removeClass("playing");

Answer 2

$(this).closest('div').removeClass("playing")

or

$(this).closest('div.playing').removeClass('playing')
