Comparison of the oscillatory behavior of a gravitating infinite Nambu-Goto string and a test string is investigated using the general relativistic gauge invariant perturbation technique with two infinitesimal parameters on a flat spacetime background. Due to the existence of the pp-wave exact solution, we see that the conclusion that the dynamical degree of freedom of an infinite Nambu-Goto string is completely determined by that of gravitational waves, which was reached in our previous works [K. Nakamura, A. Ishibashi and H. Ishihara, Phys. Rev. D 62 (2002), 101502(R); K. Nakamura and H. Ishihara, Phys. Rev. D 63 (2001), 127501], is not contrary to the dynamics of a test string. We also briefly discuss the implication of this result.
