[0002] Music is an art form and cultural activity, and its medium is sound waves that are organized in time and in a regular pattern. Its basic elements include dynamics, tonality, duration, timbre, etc. These basic elements combine to form the commonly used "formal elements" of music, such as rhythm, melody and harmony, as well as dynamics, speed, mode, form, texture, etc. The formal elements that constitute music are the means of expression of music. Different types of music may emphasize or ignore certain elements. Music is performed with a variety of instruments and vocal techniques, and is divided into instrumental music, vocal music, and works that combine singing and instruments. Music notation is a method of recording music with symbols in printing or handwriting. Different cultures and regions have developed different methods of notation. Notation can be divided into two categories: recording pitch and recording fingering. Five-line notation, simplified notation, and braille notation are all musical notations that record pitch. Six-line notation for guitar and reduced notation for guqin are all musical notations that record fingering.
