Chord Recognition- Music and Audio Information Retrieval (2105.07019v2)

Abstract: Music Information Retrieval (MIR) is a collaborative scientific study that help to build innovative information research themes, novel frameworks, and developing connected delivery mechanisms in addition to making the world's massive collection of music open for everyone. Modern rock music proved to be difficult to estimate tempo and chord recognition did not work. All of the findings indicate that modern rock and metal music can be analysed, despite its complexity, but that further research is needed in this area to make it useful. Using a neural network has been one of the simplest ways of dealing with it. The pitch class profile vector is used in the neural network method. Because the vector only contains 12 elements of semi-tone values, it is enough for chord recognition. Of course, there are other ways of achieving this work, most of them depend on pitch class profiling to transform the chord into a type that can be recognised, but the recognition process is time-consuming centred on extremely complicated and memory-intensive methods.
