  We consider a superconducting state with a mixed symmetry order parameter
components, e.g. d+is or d+id' with d'= d_{xy}. We argue for the existence of
the new orbital magnetization mode which corresponds to the oscillations of
relative phase \phi between two components around an equilibrium value of \phi
= \pi/2. It is similar to the so called ``clapping'' mode in superfluid 3He-A.
We estimate the frequency of this mode \omega_0(B,T) depending on the field and
temperature for the specific case of magnetic field induced d'= d_{xy} state.
We find that this mode is tunable with an applied magnetic field with
\omega_0(B,T) \propto B D_0, where D_0 is the magnitude of the d-wave order
parameter. We also estimate the velocity s(B,T) of this mode.
