Abstract  In the $q\bar{q}$ quark model, the states $\pi$(1300), $\eta$(1295) and $\eta$(1475) are assigned as the 21S0 meson nonet. The mass of the isodoublet remains interesting and needs further confirmation in experiments. This paper employs the phenomenological trajectory on the (N, M2)-plot and meson–meson mixing methods to calculate the mass of this state, the calculated results are 1341 MeV and 1311.58 ± 59 MeV respectively. These predictions can be compared with
experiments in the future.
