A score tracking method and apparatus are provided. The method detects
frequency models of score notes to be performed, compiles a list of
frequency models, and generates a matching model composed of frequency
components, based on the list. The frequency components are included in
audio data to be generated during a performance of the score notes. The
method then receives external audio data during an actual performance of
the score notes, converts the audio data into digital signal, and detects
current performance frequency data from the digital signal. The method
then determines whether the matching model matches the current
performance frequency data when the current performance frequency data
includes a new frequency component other than the frequency components of
the matching model, generates synchronized information between the actual
performance of the score notes and the score notes, and updates the
matching model.
