  We seek the {\em immediate} description of chiral oscillations in terms of
the trembling motion described by the velocity (Dirac) operator
{\boldmath$\alpha$}. By taking into account the complete set of Dirac equation
solutions which results in a free propagating Dirac wave packet composed by
positive and negative frequency components, we report about the
well-established {\em zitterbewegung} results and indicate how chiral
oscillations can be expressed in terms of the well know quantum oscillating
variables. We conclude with the interpretation of chiral oscillations as
position very rapid oscillation projections onto the longitudinally decomposed
direction of the motion.
