Chris@0 53 <p>
Chris@0 54 The temperament ontology can be used to give a detailed description of the tuning of an instrument.
Chris@0 55 It is developed in the OMRAS2 project, and intended to be used in conjunction
Chris@0 56 with the <em><a href="http://purl.org/ontology/mo/">Music Ontology</a></em>,
Chris@0 57 for example, when describing the tuning that was used in a particular harpsichord recording.

Chris@0 102
Chris@0 103 <h2 id="intro">1 Introduction</h2>
Chris@0 104
Chris@0 105 <p>The temperament ontology aims to describe instrument tuning systems and their particularities.
Chris@0 106 It may also be used to characterise a (potentially unknown) temperament that was used when tuning an
Chris@0 107 instrument for a particular performance or recording. <br><br>
Chris@0 108 At this stage the ontology is far from exhaustive. We primarily deal with
Chris@0 109 temperaments in western tonal music with an emphasis on tuning keyboard instruments.
Chris@0 110 One important objective is to be able to describe arbitrary temperaments,
Chris@0 111 or express the results of automatic temperament extraction from audio recordings.
Chris@0 112 </p>
Chris@0 113
Chris@0 114 <h3 id="s11">1.1 About instrument tuning</h3>
Chris@0 115
Chris@0 116 <p>Tuning an instrument consists of choosing the frequency values and spacing (or ratio) of pitches that are used.
Chris@0 117 Pure (just) intervals of pitches correspond to whole number ratios of their frequencies, however
Chris@0 118 these ratios are not compatible with each other as they arranged in scales (the way octaves are divided into discrete pitch classes) in western music.
Chris@0 119 For example, it is not possible to fit twelve pure fifths (3:2)^12 into seven octaves (2:1)^7. The difference
Chris@0 120 is called the Pythagorean or Ditonic comma (23.5 cents). This difference has to be
Chris@0 121 tempered out ---that is, some (or all) fifths has to be mistuned slightly in order to
Chris@0 122 fit them. There are many tuning systems. Most commonly, they differ in the way they compromise
Chris@0 123 pure intervals to solve this problem. </p>
Chris@0 124
Chris@0 125
Chris@0 126 <h3 id="s12">1.2 An open-ended temperament description model</h3>
Chris@0 127 <p>There is no mutual agreement in the literature on the description or classification
Chris@0 128 of temperaments. Therefore, in this ontology we do not impose a
Chris@0 129 hierarchy between types of temperaments. We define an opaque
Chris@0 130 top-level temperament concept. Subclasses of this concept can be used
Chris@0 131 in describing individual temperaments, if necessary, using multiple class memberships.
Chris@0 132 Since there is more than one way to associate tuning systems with their properties,
Chris@0 133 we treat temperament descriptions as concepts as well,
Chris@0 134 and use reification to keep the model open and extensible.</p>

Chris@0 139
Chris@0 140 <h3 id="s13">1.3 The many ways of describing temperaments</h3>
Chris@0 141
Chris@0 142 <p>Temperaments can be characterised in lots of different ways.
Chris@0 143 The most common methods are using either the circle of fifths or
Chris@0 144 give the pitch deviations from equal temperament. We define these
Chris@0 145 descriptions as concepts in the ontology, however, other descriptions
Chris@0 146 may be used and defined in the future.
Chris@0 147 (For example, one might find it convenient to express the same information using the circle of fourths.)</p>
Chris@0 148
Chris@0 149 <h4 id="s131">1.3.1 The Circle of Fifths</h4>
Chris@0 150 The circle of fifths has several uses in music theory.
Chris@0 151 It shows the harmonic relationships of the twelve major and minor keys.
Chris@0 152 It can also be seen as a circle of the corresponding pitch class intervals,
Chris@0 153 such as (C-G), (G-D), (D-A) etc... If we go around the circle using pure fifth
Chris@0 154 intervals, it wouldn't close. What remains is the Pythagorean comma.
Chris@0 155 Hence, it is often used to describe temperaments by showing how
Chris@0 156 the comma is distributed among the intervals to close the circle.
Chris@0 157 (Note that there are several types of commas related to different
Chris@0 158 tuning problems. These are defined in the ontology.)
Chris@0 159
Chris@0 160 <!--<p><center><img src="CircleOfFifths.png" alt="Using the Circle of Fifths to describe a temperament." width="350"></center></p>-->
Chris@0 161
Chris@0 162 <p>...</p>
Chris@0 163
Chris@0 164 <h4 id="s132">1.3.2 Deviations from Equal Temperament</h4>
Chris@0 165
Chris@0 166 <p>In equal temperament an octave is divided into twelve equal intervals.
Chris@0 167 As a result only octaves are pure. All other intervals are impure, and the
Chris@0 168 deviation from pure is different in case of each interval. Since equal temperament
Chris@0 169 has become very common, other temperaments are often described by
Chris@0 170 the frequency deviations (in cents) of each pitch class from the
Chris@0 171 corresponding pitch class in equal temperament.</p>

Chris@0 232 The IntervalDeviation concept describes the amount of deviation from a pure interval
Chris@0 233 in terms of a specific type of comma and a corresponding value (a fraction of that comma).
Chris@0 234 We can safely assume that a fifth is pure, unless the deviation is given.</p>
