An ideal massless spring, fixed at one end and with a free mass attached at the other end, will have a distinct oscillation frequency depending on its spring constant and the mass.
A spring with mass along its length, on the other hand, will not have a characteristic oscillation frequency. Instead, it will now have a wave SPEED, depending on its spring constant and mass per length. All wavelengths and frequencies would be possible, so long the product f λ = S, where S is the wave speed of the spring. If this sounds like longitudinal waves, like sound waves in solids, you're right, it's like that.
