We discuss the phenomenology of the isocurvature perturbations which are correlated with the curvature perturbations. We show how precisely the forthcoming CMB experiments can constrain such correlated isocurvature perturbations. We also illustrate how the correlated isocurvature perturbations help in discriminating the axion inflation scenarios.
