In [http://en.wikipedia.org/wiki/Music_theory music theory], an '''interval''' is a combination of [[two]] [[notes]], or the [[ratio]] between their [[frequencies]]. Two-note combinations are also called [http://en.wikipedia.org/wiki/Dyad_(music) dyads]. Although [http://en.wikipedia.org/wiki/Chord_(music) chords] are often defined as sets of three or more notes, intervals are sometimes considered to be the simplest kind of chord.

In [http://en.wikipedia.org/wiki/Western_culture Western culture], the most common [[method]] to [[classify]] and name intervals is based on their [[quality]] (perfect, major, minor, etc.) and [[number]] (unison, second, third, etc.). For instance, two frequently used types of interval are called minor third and major third. Intervals may be also [[classified]] as:

Minute intervals ([http://en.wikipedia.org/wiki/Comma_(music) commas], and [http://en.wikipedia.org/wiki/Microtone microtones]) can be formed by the notes of musical scales containing more than 12 pitches (e.g., by the notes A♭ and G♯ found in some [http://en.wikipedia.org/wiki/Five-limit_tuning#Extension_of_the_twelve_tone_scale extended scales]), or by two notes having the same name, but tuned a different way (e.g., the [http://en.wikipedia.org/wiki/Syntonic_comma syntonic comma] is sometimes defined as the [[difference]] between an F♯ tuned using the D-based [http://en.wikipedia.org/wiki/Pythagorean_tuning Pythagorean system], and another F♯ tuned using the D-based [http://en.wikipedia.org/wiki/Quarter-comma_meantone quarter-comma meantone system]). They are sometimes so small that the [[difference]] in [[pitch]] between the two notes cannot be [[perceived]].[http://en.wikipedia.org/wiki/Interval_%28music%29]
