Tritone

In classical music from Western culture, the tritone ( Play (help·info), tri- "three" and tone) is traditionally defined as a musical interval composed of three whole tones. In a chromatic scale, each whole tone can be further divided into two semitones. In this context, a tritone may also be defined as any interval spanning six semitones.

Since a chromatic scale is formed by 12 pitches, it contains 12 distinct tritones, each of which starting from a different pitch. According to a widely used naming convention, six of them are classified as augmented fourths, and the other six as diminished fifths. In a diatonic scale there is only one tritone, classified as an augmented fourth. For instance, in the C major diatonic scale the only interval formed by three adjacent tones (F-G, G-A, and A-B) is that from F to B.

In the above-mentioned naming convention, a fourth is an interval encompassing four staff positions, while a fifth encompasses five staff positions (see interval number for more details). The augmented fourth (A4) and diminished fifth (d5) are defined as the intervals produced by widening and narrowing by one chromatic semitone the perfect fourth and fifth, respectively. They both span six semitones, and they are the inverse of each other, meaning that their sum is exactly equal to one perfect octave (A4 + d5 = P8). In 12-tone equal temperament, the most commonly used tuning system, the A4 is equivalent to a d5, as both have the size of exactly half an octave. In most other tuning systems, they are not equivalent, and neither is equal to half an octave. The d5 is also called semidiapente.

Propaganda

Why don't you get a life and grow up
Why don't you realize that you're fucked up
Why criticize what you don't understand
Why change my words, you're so afraid
You think you have the right to put me down
Propaganda hides your scum
Face to face you don't have a word to say
You got in my way, now you'll have to pay
Don't, don't believe what you see
Don't, don't believe what you read

Britain should stop trying to pretend that its empire was benevolent

Edit Dawn 20 May 2016

The recent debacle of David Cameron’s filmed condemnation of Nigerian and Afghan corruption and the Queen’s remark on Chinese officials’ rudeness highlights the persistence of imperial thinking in Britain.
