Cipher Notation

Rousseau Melody Notation (app for cipher notation as described by Jean Jaques Rousseau)
Scale Degrees
Cipher notation (or numbered musical notation) uses the numerals 1 through 7 to indicate the scale degrees ('musical notes') of the heptatonic (7-note) 'major' scale (do re mi fa sol la ti). 

     1   .   2   .   3   4   .   5   .   6   .   7
     do  .   re  .   mi  fa  .   sol .   la  .   ti

'1' represents the root of the scale, which can be based on any pitch and is determined by the performer. Thus, all the intervals of the scale are measured relative to that root.

               1   .   2   .   3   4   .   5   .   6   .   7
     From C :  C   .   D   .   E   F   .   G   .   A   .   B
                  
     From Bb:  Bb  .   C   .   D   Eb  .   F   .   G   .   A
                  
     From E :  E   .   F#  .   G#  A   .   B   .   C#  .   D#
             

A dot above a number raises the pitch of the note by an octave, a dot below, lowers the pitch by an octave

Accidentals

Any variation to the interval structure of the major scale is indicated with 


Rhythm Durations

Basic rhythmic durations are indicated in the following ways.
The system is not well-suited to complex rhythmic patterns.

Each degree is equal in duration unless otherwise indicated:

        1   2   3   5   4   3   2   1 
        x   x   x   x   x   x   x   x
    

A line above two or more notes groups them into a subdivision of the beat

A dash extends the duration of the note by one unit.
