<p>Make sure that your daughter’s vocal training is being done by vocal technique teacher who knows what is expected in the musical theatre world and knows how to teach your D to do that healthily and knowledgeably. “Classical training” does not necessarily align with healthy and competitive MT singing - so your D should be with a teacher who understands that belting or mix-belting (the terms are not agreed upon) are:</p>
<ol>
<li>NOT innately unhealthy</li>
<li>call for some VERY different physical engagements from classical singing</li>
</ol>
<p>And also, that classical singing for voice performance and legit MT singing have some differences in presentation, although the technical differences are not wide</p>
<p>ANY teacher who says belting is innately “unhealthy” or says students should wait til a certain standard age to belt is medically incorrect and will not help your daughter achieve her MT goals.</p>
