Descripción: We propose that the phonons in <math>{}^4He\!\,</math> obey a q-deformation of the Heisenberg algebra and give an algebraic interpretation for the polynomial expansion of the small momenta phonon dispersion relation. Comparison with <math>C_V\,\!</math> experimental data shows that our spectrum reproduces the experimental one within less than <math>5%\,\!</math> of discrepancy.
