<en>The following is intented to briefly describe how musical notation
is typically written when using <a href="http://en.wikipedia.org/wiki/Braille">Braille</a>
(a tactile form of reading and writing for the blind).</en>
<de>Im folgenden Text soll kurz beschrieben werden wie die grafische

<p>
<en>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.</en>
