<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">properly pitched</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 tuned that I've seen before include "Adjusted a radio or engine" , "Correctly adjusted (eg in pitch)" , "Adjusted (musical) pitch" , "Given the correct pitch" , "desired pitch" .)
