Introduction
This document is a very first draft of a tuning RDF description developed in the Centre for Digital Music, Queen Mary, University of London as part of the OMRAS2 project. The objective of this ontology is to describe Tuning Systems as support for the Tonality Ontology. It is also conceived to be helpful describing the tuning of an instrument or a band so it has been splitted up as another ontology module.
All feedback is welcome and if you would like to propose changes or additions to the ontology, the best place to do so is on the Music Ontology mailing list. If you prefer, please feel free to contact the author of the document.

The author would like to thank the Centre for Digital Music and the Music Ontology Community for the necessary support to develop this work.
The design and layout of this ontology document is based on the Music Ontology and FOAF Vocabulary specification documents.
Namespaces
Several namespaces will be assumed to have been defined for the remainder of this document. These are as follows :
Overview of Terms
An alphabetical index of the ontology terms, divided into classes, properties and individuals. All the terms are hyperlinked to their detailed description for quick reference.
Ontology Terms
Classes
Class: tuning:EqualTemperament - unstable -
EqualTemperament
- Temperament adjusts the intervals of the octave dividing it in equal steps.
[back to top]
Class: tuning:InstrumentTuning - unstable -
InstrumentTuning
- Class representing the specific tuning of an instrument.
[back to top]
Class: tuning:JustIntonation - unstable -
JustIntonation
- Tuning system where intervals are just related by rationale number ratios.
[back to top]
Class: tuning:Tuning - unstable -
Tuning
- Class representing the specific tuning.
[back to top]
Class: tuning:TuningSystem - unstable -
TuningSystem
- Class representing the tuning of the octave.
[back to top]
Class: tuning:WellTemperament - unstable -
WellTemperament
- Temperament adjusts the intervals of the octave so the progression of interval is circular but not through equal intervals.
[back to top]
Properties
Property: tuning:frequency_A - unstable -
frequency_A - tuning of an instrument given the exact frequency for A
Property: tuning:octave_divisions - unstable -
octave_divisions - Number of divisions within the octave.
Individuals
Individual: meantone -
Meantone Temperament - The meantone temperament (just intonation).
Individual: twelve_edo -
edo 12 - equal division of the octave in twelve steps.
