Why should some keys be more difficult to read than others?

Modulo Notation has its own intonation system and key signatures although these are not strictly necessary to be able to read the music. Modulo can thus preserve all information contained in traditional notation. Its intonation system is more or less "key neutral" in that it treats all keys in a similar way. It is strongly recommended to use these alternative key signatures and accidentals in tonal music since they can effectively have an impact upon the interpretation of a piece.

Although Modulo is a notation suitable for all kinds of musical instruments, it is especially well suited for the CBA (chromatic button accordion). The first row of a CBA will be represented by hollow note heads; the second row will have solid black note heads placed on lines; the third row will have solid black note heads between lines.

SaLaTa is the note naming, interval naming, and chord symbol system that Modulo always uses. The document also shows how to analyze music using SaLaTa.

This new rhythm notation system is the default rhythm system for Modulo Notation. It is designed to be clear, uncomplicated and intuitive, yet still very versatile.

Each and every note's relation to the beat structure will always be evident. A beam always represent one beat. Since all beats take up an equal amount of time, it is clear that all stems on a beam should be played within the time frame of one beat. So, the more stems there are, the faster they should be played.

The PDF primer to Modulo Notation. The Features link above, provides references to this document. The primer also shows an example of what the new notation looks like in action, compared to traditional notation, with an excerpt from Claude Debussy's "Ce qu'a vu le vent d'Ouest". In that particular excerpt, Modulo Notation can preserve and present all information from traditional notation. The Modulo version, however, uses a different key signature to reduce the number of accidentals, but could also have been written in the original key signature. It is less of a problem to switch key signatures more frequently in Modulo.

The traditional version of the excerpt actually has an inconsistency with regards to rhythm that the new notation was able to solve without adding too much complexity.

The MNP (Music Notation Project) has a wiki page where a specific excerpt of music, written for pipe organ, is being represented in a number of different musical notations. The following document shows what this particular excerpt (from MacFarlane's "Spring Song") looks like in Modulo Notation.
