The main two differences to the traditional notation are:

  1. Each note keeps its relative position to the thin and thick lines consistent across different octaves.
  2. A note corresponding to a white key is black and a note corresponding to a black key is white.

 

1. The positions of each note

F

A note resting over an F-line is an F:

 

f

 

 

f

 

B

Directly under the two C-lines

 

f

 

 

D & A

At both sides of the two C-lines

 

f

 

E & G

At both sides of the F-line

 

f
 

 

2. Accidentals and Key Signatures

 
The traditional notation uses a key signature which designates notes which are to be consistently played a semitone higher or lower than each natural equivalent. This forces the reader to remember the last key signature and the accidentals which happen before each note in order to recognize the emitone of each note. 

Key signature and accidentals aren’t used in the Leszer notation. Instead a note adopt a color, depending on whether it represents a white or a black key on the piano.   

 

Example (Comparison between traditional and Leszer Notation)

f

f

This rule removes all accidentals making easier to recognize which key corresponds to which note. Following example shows an excerpt of the fantasie-impromptu of Chopin in both notations

 

f

 

 In the Leszer notation, a sharp (#), a double sharp(x) or a natural note are equally complex represented: just a symbol.

Thanks for your comments.

At first it was black keys black notes and white keys white notes, but soon after I realized the sheet music looked too bizarre, because most of the notes where white; so I decided to reverse the colors. Now it is admitedly less logical, but the sheet musics look more like the traditional ones.

I added a scale of white and black keys: http://www.leszer.net/index.php/leszer-notation.html

Hi there

I do not play piano , or read music , So if you are simplyfying music notation , why did you make black keys , white notes and white keys , black notes ?

What do you call the black keys in your notation ?

It would help me if you showed all the keys ( black and white ) in ONE diagram

thank you
