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

<h2 id="intro">1 Introduction</h2> |
| 104 |
|
| 105 |
<p>The temperament ontology aims to describe instrument tuning systems and their particularities. |
| 106 |
It may also be used to characterise a (potentially unknown) temperament that was used when tuning an |
| 107 |
instrument for a particular performance or recording. <br><br> |
| 108 |
At this stage the ontology is far from exhaustive. We primarily deal with |
| 109 |
temperaments in western tonal music with an emphasis on tuning keyboard instruments. |
| 110 |
One important objective is to be able to describe arbitrary temperaments, |
| 111 |
or express the results of automatic temperament extraction from audio recordings. |
| 112 |
</p> |
| 113 |
|
| 114 |
<h3 id="s11">1.1 About instrument tuning</h3> |
| 115 |
|
| 116 |
<p>Tuning an instrument consists of choosing the frequency values and spacing (or ratio) of pitches that are used. |
| 117 |
Pure (just) intervals of pitches correspond to whole number ratios of their frequencies, however |
| 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. |
| 119 |
For example, it is not possible to fit twelve pure fifths (3:2)^12 into seven octaves (2:1)^7. The difference |
| 120 |
is called the Pythagorean or Ditonic comma (23.5 cents). This difference has to be |
| 121 |
tempered out ---that is, some (or all) fifths has to be mistuned slightly in order to |
| 122 |
fit them. There are many tuning systems. Most commonly, they differ in the way they compromise |
| 123 |
pure intervals to solve this problem. </p> |
| 124 |
|
| 125 |
|
| 126 |
<h3 id="s12">1.2 An open-ended temperament description model</h3> |
| 127 |
<p>There is no mutual agreement in the literature on the description or classification |
| 128 |
of temperaments. Therefore, in this ontology we do not impose a |
| 129 |
hierarchy between types of temperaments. We define an opaque |
| 130 |
top-level temperament concept. Subclasses of this concept can be used |
| 131 |
in describing individual temperaments, if necessary, using multiple class memberships. |
| 132 |
Since there is more than one way to associate tuning systems with their properties, |
| 133 |
we treat temperament descriptions as concepts as well, |
| 134 |
and use reification to keep the model open and extensible.</p> |
| 135 |

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

<p>A graphical representation of a similar description is shown in figure 2. |
| 231 |
We explicitly name the pitch classes involved in each interval on the circle of fifths. |
| 232 |
The IntervalDeviation concept describes the amount of deviation from a pure interval |
| 233 |
in terms of a specific type of comma and a corresponding value (a fraction of that comma). |
| 234 |
We can safely assume that a fifth is pure, unless the deviation is given.</p> |
