numbered musical notations

Machine-translated from the Portuguese article

Numbered musical notation is a coded notation system used in China, and to some extent in Japan, Indonesia, Malaysia, Australia, Ireland, the United Kingdom, the United States, and the English-speaking part of Canada. This numerical musical notation essentially uses digits (1 to 7, with 0 as a rest), together with additional characters, including many from standard Western musical notation. The system is very popular among some Asian peoples, making the conventions for encoding and decoding music more accessible than in the West, since more Chinese people can read jianpu at sight than standard notation.
