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

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