      abstract     = {We study the pattern of oscillations in the primordial
                      power spectrum in axion monodromy inflation, accounting for
                      drifts in the oscillation period that can be important for
                      comparing to cosmological data. In these models the
                      potential energy has a monomial form over a super-Planckian
                      field range, with superimposed modulations whose size is
                      model-dependent. The amplitude and frequency of the
                      modulations are set by the expectation values of moduli
                      fields. We show that during the course of inflation, the
                      diminishing energy density can induce slow adjustments of
                      the moduli, changing the modulations. We provide templates
                      capturing the effects of drifting moduli, as well as drifts
                      arising in effective field theory models based on softly
                      broken discrete shift symmetries, and we estimate the
                      precision required to detect a drifting period. A
                      non-drifting template suffices over a wide range of
                      parameters, but for the highest frequencies of interest, or
                      for sufficiently strong drift, it is necessary to include
                      parameters characterizing the change in frequency over the
                      e-folds visible in the CMB. We use these templates to
                      perform a preliminary search for drifting oscillations in a
                      part of the parameter space in the Planck nominal mission
