The Leszer Notation is my personal attempt to make music more readable. It was developed to maximize the ease of reading of music and the resemblance to the traditional Notation. Although it can be used for any musical instrument, the main focus was piano (mainly because I don't play any other instrument).
The Leszer Notation is a diatonic system like the traditional notation. This means that the notes, which represent black and white keys in a piano, share the same position in the staff. Unlike traditional notation though, the color of the note determines whether the note represents a black or a white key. This releases the musician from the task of remembering which accidentals apply to each note. This property makes the key signature also superfluous.
In traditional notation, different clefs determine which tone in which octave is represented by each note. The Leszer Notation replaces the clef by a octave-marker, eliminating the problem of making the position of the note dependent of the clef without renouncing to the octave information.
With the traditional staff, two notes an octave apart from each other bear no visual similarity, which means that you have to learn to associate two or three sets of positions to the same note (one set per octave). The Leszer Notation overcomes this problem by substituting the traditional staff by a pattern of lines, which is repeated across octaves. This pattern of lines is composed of four thin lines and one thicker line, making a set of five lines like in the traditional notation. Through the position and the thickness of the lines the goal is achieved: each note has the same position over the line pattern, regardless of its octave.
The main advantages of this notation are:
