AB  - The COMPASS experiment has taken a large data set with a negative pion beam impinging on a liquid-hydrogen target to study the spectrum of light mesons in diffractive dissociation reactions. The properties of known resonances are studied, and new, possibly spin-exotic states are searched in three-pion final states. A new state at about 1.4 GeV/c<sup>2</sup> with a<sub>1</sub> quantum numbers is observed in the decay to f<sub>0</sub>(980)π. The spin-exotic 1<sup>−+</sup> wave is investigated in order to search for the controversial π<sub>1</sub>(1600).
