We analyze observational signatures that may arise from a cosmological epoch corresponding to the simple harmonic universe, which consists of positive curvature, a negative cosmological constant, and one or more matter sources with an intermediate equation of state, which then tunnels and/or evolves into inflation and radiation-dominated eras. We find that the effects on the cosmic microwave background and matter power spectrum from additional matter sources are subdominant to the effects arising due to curvature alone. Moreover, even if the curvature is too small to detect at late times, it can modify the primordial power spectrum, and may help explain the observed suppression of the CMB TT quadrupole in the Planck satellite data
