Placing rhythms on a circle gives a good multisensory window into ratios and angles. Wave mechanics The brain turns out to be adept at decomposing sinusoids into their component frequencies.

If two pitches share a lot of overtones, we tend to hear them as consonant, at least here in the western world. The relationship between absolute pitches and pitch classes is an excellent doorway into logarithms generally. You also need logarithms to understand decibels and loudness perception. Symmetry Music is really just a way of applying symmetry to events in time. See this delightful paper by Vi Hart about symmetry and transformations in the musical plane. Combinatorics and graph theory Generating diatonic chords from a scale is an exercise in combinatorics.

The tempering can involve either the irregularities of well temperament or be constructed as a regular temperamenteither some form of equal temperament or some other regular meantone, but in all cases will involve the fundamental features of meantone temperament. For example, the root of chord ii, if tuned to a fifth above the dominant, would be a major whole tone 9: If tuned a just minor third 6: Meantone temperament reduces the difference between 9: Equal temperament tunings[ edit ] In equal temperamentthe octave is divided into equal parts on the logarithmic scale.

While it is possible to construct equal temperament scale with any number of notes for example, the tone Arab tone systemthe most common number is 12, which makes up the equal-temperament chromatic scale.

In western music, a division into twelve intervals is commonly assumed unless it is specified otherwise. For the chromatic scale, the octave is divided into twelve equal parts, each semitone half-step is an interval of the twelfth root of two so that twelve of these equal half steps add up to exactly an octave.

With fretted instruments it is very useful to use equal temperament so that the frets align evenly across the strings. In the European music tradition, equal temperament was used for lute and guitar music far earlier than for other instruments, such as musical keyboards.

Because of this historical force, twelve-tone equal temperament is now the dominant intonation system in the Western, and much of the non-Western, world. Equally tempered scales have been used and instruments built using various other numbers of equal intervals.

The 19 equal temperamentfirst proposed and used by Guillaume Costeley in the 16th century, uses 19 equally spaced tones, offering better major thirds and far better minor thirds than normal semitone equal temperament at the cost of a flatter fifth.

The overall effect is one of greater consonance. Twenty-four equal temperamentwith twenty-four equally spaced tones, is widespread in the pedagogy and notation of Arabic music.
