The excitation of flavor of composite fermions across composite-fermion quasi-Landau levels (LL) was investigated. It was found that a ladder of flavor changing excitations exists in which composite fermions were partially dissociated by a removal of some or all of their velocities. It was found that the collective excitations evolve continously not only across fractions belonging to a given sequence, but also between different sequences of fractions. The zero wave vector mode, the minimum energy neutral excitation and the excitation that contains a far separated particle hole pair of composite fermions was observed.
