  We propose a novel approach to construction of hadron spectroscopy. The case
of light nonstrange mesons is considered. By assumption, all such mesons above
1 GeV appear due to creation of constituent quark-antiquark pairs inside the pi
or rho (omega) mesons. These spin-singlet or triplet pairs dictate the quantum
numbers of formed resonance. The resulting classification of light mesons turns
out to be in a better agreement with the experimental observations than the
standard quark model classification. It is argued that the total energy of
quark components should be proportional to the hadron mass squared rather than
the linear mass. As a byproduct a certain relation expressing the constituent
quark mass via the gluon and quark condensate is put forward. We show that our
approach leads to an effective mass counting scheme for meson spectrum and
results in the linear Regge and radial Regge trajectories by construction. An
experimental observation of these trajectories might thus serve as an evidence
not for string but for multiquark structure of highly excited hadrons.
