Abstract
We study the meson spectroscopy allowing the mixture of conventional wave quark-antiquark states and four-quark components. A similar picture was used to describe the new and open charm mesons. The four-quark components shift the masses of some positive parity states below their corresponding isospin preserving two-meson threshold and therefore they are expected to be narrow. Electromagnetic decay widths are analyzed.
