A method and system for determining a hydrocarbon dewpoint of natural gas in which a spherical acoustic resonator is filled with natural gas at a first temperature and pressure, where the first temperature is above the hydrocarbon dewpoint at the pressure. An acoustic signal is introduced into the natural gas and the radial resonance frequency of the natural gas is measured as the temperature of the natural gas is reduced. As the temperature decreases, the radial resonance frequency also decreases. The hydrocarbon dewpoint is the temperature at which the radial resonance frequency is at a minimum.
