The music signal was divided into several subsections and the length of each section was equal to the duration of one semiquaver. The base frequency was obtained using one dimension DCT operated on each section. The extreme points of the musical notes were found by comparison with the adjacent sub-sections. And then, the musical scores were got using the principle of least derived notes.
