A model for a chromospheric resonator for slow waves is proposed, and its basic features are compared with those of the model for a photospheric resonator for fast waves, proposed by Thomas and Scheuer (1982), (TS). Moreover, the model predictions are tested for agreement with recent observations of umbral oscillations. The observations in the umbral chromosphere and transition region are in agreement with the model presented but are difficult to reconcile with the TS model. This conclusion does not exclude the possibility that a TS-type photospheric resonator is excited as well. Finally, necessary improvements in the existing simplified theories are outlined.
