<b>Flavor Mixing and Chiral Symmetry for Mesons with Higher Spin,
and<br>
the Effect of Tetraquarks on the Chiral Phase Transition</b><br>
<br>
I discuss two topics: 1) how the axial U_A(1) anomaly affects
flavor mixing in mesons with spin<br>
two and higher; and 2) how the appearance of tetraquarks can lead
to dramatic effects for the <br>
chiral transition with three (but not two) light flavors. </div>
