Braille Music Notation is a fourth type of braille. It is used for reading and writing music notation. It consists of all of the necessary symbols for transcribing instrumental, vocal, and choral scores. Finally, there is the Code of Braille Textbook Formats. This fifth type of braille is a combination of the other four codes and is used in the production of all school textbooks in braille.
Braille is read by lightly moving the fingers from left to right across the line of Braille.
Most people start out learning to read using cells smaller than the one represented above, and the regular Braille user reads much smaller cells. Braille was first developed in 1824 by a 15 year old French student named Louis Braille. Mr. Braille, who was blind, wanted a better way to read and write. The raised dot system that he invented grew out of another code developed for sending military messages that could be read on the battlefield in the dark of the night. Braille has been improved and refined many times in the United States and other countries since it was first developed.
