The following is intented to briefly describe how musical notation is typically written when using Braille (a tactile form of reading and writing for the blind). ...
Since vertical alignment is not used in braille music, a note in braille music unifies the pitch and duration of the note in one symbol Since the amount of avaiable different braille symbols is pretty limited with 6-dot braille, a compromise had to be taken. The symbols for a whole and a sixteen note are the same, as well as the symbol for a half and thirtyeighth note and so on.
