Numeral prefix

Numeral or number prefixes are prefixes derived from numerals or occasionally other numbers. In English and other European languages, they are used to coin numerous series of words, such as unicycle – bicycle – tricycle, dyad – triad – decade, biped – quadruped, September – October – November – December, decimal – hexadecimal, sexagenarian – octogenarian, centipede – millipede, etc. There are two principal systems, taken from Latin and Greek, each with several subsystems; in addition, Sanskrit occupies a marginal position. There is also an international set of metric prefixes, which are used in the metric system, and which for the most part are either distorted from the forms below or not based on actual number words.

In the following prefixes, a final vowel is normally dropped before a root that begins with a vowel, with the exceptions of bi-, which is bis- before a vowel, and of the other monosyllables, du-, di-, dvi-, tri-, which are invariable.

Advanced and retracted tongue root

In phonetics, advanced tongue root and retracted tongue root, abbreviated ATR or RTR, are contrasting states of the root of the tongue during the pronunciation of vowels in some languages, especially in West and East Africa but also in Kazakh and Mongolian. It used to be suggested that it was the basis for the distinction between tense and lax vowels in European languages such as German, but it is no longer seems tenable.

Advanced tongue root

Advanced tongue root, abbreviated ATR or +ATR, also called expanded, involves the expansion of the pharyngeal cavity by moving the base of the tongue forward and often lowering the larynx during the pronunciation of a vowel. The lowering of the larynx sometimes adds a breathy quality to the vowel.

Voiced stops such as [b], [d], [g] can often involve non-contrastive tongue root advancement whose results can be seen occasionally in sound changes relating stop voicing and vowel frontness such as voicing stop consonants before front vowels in the Oghuz Turkic languages or in Adjarian's law: the fronting of vowels after voiced stops in certain dialects of Armenian.

ATR 42

The ATR 42 is a twin-turboprop, short-haul regional airliner built in France and Italy by ATR (Aerei da Trasporto Regionale or Avions de transport régional). ATR models have their final assembly in Toulouse, and share resources and technology with Airbus. The name "42" comes from the aircraft's standard seating, which varies from 40 to 52. The aircraft serves as the basis for the larger ATR 72.

Design and development

The ATR 42–300 was announced in 1981, making its maiden flight on 16 August 1984; French and Italian certification followed in September 1985 and its first revenue flight was in December with Air Littoral of France. This initial version of the ATR 42 was in production until 1996. The next upgrade for the product was the ATR 42-320 (also produced until 1996); this variant differed in that it was equipped with the more-powerful PW-121 engines for improved performance. The ATR 42-300QC is a quick-change (convertible) freight/passenger version of the standard −300 series.

The current production version is the −500 series. It is a next-generation aircraft with new engines, new propellers, improved hot and high performance, increased weight capacity and an improved passenger cabin. The 50-seat ATR 42–500 was first certificated in July 1995.

Harmony

In music, harmony is the use of simultaneous pitches (tones, notes), or chords. The study of harmony involves chords and their construction and chord progressions and the principles of connection that govern them. Harmony is often said to refer to the "vertical" aspect of music, as distinguished from melodic line, or the "horizontal" aspect.Counterpoint, which refers to the interweaving of melodic lines, and polyphony, which refers to the relationship of separate independent voices, are thus sometimes distinguished from harmony.

In popular and jazz harmony, chords are named by their root plus various terms and characters indicating their qualities. In many types of music, notably baroque, romantic, modern, and jazz, chords are often augmented with "tensions". A tension is an additional chord member that creates a relatively dissonant interval in relation to the bass. Typically, in the classical common practice period a dissonant chord (chord with tension) "resolves" to a consonant chord. Harmonization usually sounds pleasant to the ear when there is a balance between the consonant and dissonant sounds. In simple words, that occurs when there is a balance between "tense" and "relaxed" moments.

Harmony (Three Dog Night album)

Harmony is the seventh album by American rock band Three Dog Night, released in 1971 (see 1971 in music). The album featured two Top 10 hits: a cover version of Paul Williams' "An Old Fashioned Love Song" (U.S. #4) and Hoyt Axton's "Never Been to Spain" (U.S. #5).
