COMPASS is a multipurpose fixed target experiment at CERN using muon and hadron beams of high intensity
for study of hadron structure and hadron spectroscopy.
The precision test of the chiral perturbation theory predictions using charged pion scattering
off a virtual photon with small momentum transfer is one of the main points of the COMPASS physics programme.
The important results for the charged pion polarizability, radiative widths of $a_2(1320)$ and $\pi_2(1670)$ mesons
and the cross section dynamics for the reactions $\gamma^*\pi^{-}\rightarrow 3\pi$ are obtained recently.
The new results and perspectives for search for photo(lepto-)production of exotic charmonium-like states are also reported.
