<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">ballroom dance in triple time</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for waltz that I've seen before include "German dance" , "Ballroom dance in triple time" , "A flowing melody or dance in triple time" , "Last dance?" , "The 123, 123 ballroom dance" .)
