<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">musical compositions</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 sonatas that I've seen before include "10 [COMPOSITION]s" , "eg Moonlight and Waldstein" , "Classical pieces" , "musical items" , "Instrumental compositions" .)
