The 2:1 resonance between the fundamental and the second overtone modes has received a great deal of attention in the context of Cepheids. It was clearly shown that it causes the Hertzsprung bump progression and brings about the very characteristic observed variation of the Fourier phases with period (Buchler & Goupil, 1984, Ap.J.,279, 394; Klapp, Goupil & Buchler, 1985, Ap.J.,296, 514; Buchler & Kovacs, 1986, Ap.J.,303, 749).
