Mode (music) in the context of "Ionian mode"

Gregorian chant is the central tradition of Western plainchant, a form of monophonic, unaccompanied sacred song in Latin (and occasionally Greek) of the Roman Catholic Church. Gregorian chant developed mainly in western and central Europe during the 9th and 10th centuries, with later additions and redactions. Although popular legend credits Pope Gregory I with inventing Gregorian chant, scholars believe that he only ordered a compilation of melodies throughout the whole Christian world, after having instructed his emissaries in the Schola Cantorum, where the neumatical notation was perfected, with the result of most of those melodies being a later Carolingian synthesis of the Old Roman chant and Gallican chant.

Gregorian chants were organized initially into four, then eight, and finally 12 modes. Typical melodic features include a characteristic ambitus, and also characteristic intervallic patterns relative to a referential mode final, incipits and cadences, the use of reciting tones at a particular distance from the final, around which the other notes of the melody revolve, and a vocabulary of musical motifs woven together through a process called centonization to create families of related chants. The scale patterns are organized against a background pattern formed of conjunct and disjunct tetrachords, producing a larger pitch system called the gamut. The chants can be sung by using six-note patterns called hexachords. Gregorian melodies are traditionally written using neumes, an early form of musical notation from which the modern four-line and five-line staff developed. Multi-voice elaborations of Gregorian chant, known as organum, were an early stage in the development of Western polyphony.

Musica enchiriadis is an anonymous musical treatise authored during the 9th century. It is the first surviving attempt to set up a system of rules for polyphony in western art music. The treatise was once attributed to Hucbald, but this is no longer accepted. Some historians once attributed it to Odo of Cluny (879–942). It has also been attributed to Abbot Hoger (d. 906).

This music theory treatise, along with its companion text, Scolica enchiriadis, was widely circulated in medieval manuscripts, often in association with Boethius' De institutione musica. It consists of nineteen chapters; the first nine are devoted to notation, modes, and monophonic plainchant.

Impressionism in music was a movement among various composers in Western classical music (mainly during the late 19th and early 20th centuries) whose music focuses on mood and atmosphere, "conveying the moods and emotions aroused by the subject rather than a detailed tone‐picture". "Impressionism" is a philosophical and aesthetic term borrowed from late 19th-century French painting after Monet's Impression, Sunrise. Composers were labeled Impressionists by analogy to the Impressionist painters who use starkly contrasting colors, effect of light on an object, blurry foreground and background, flattening perspective, etc. to make the observer focus their attention on the overall impression.

The most prominent feature in musical Impressionism is the use of "color", or in musical terms, timbre, which can be achieved through orchestration, harmonic usage, texture, etc. Other elements of musical Impressionism also involve new chord combinations, ambiguous tonality, extended harmonies, use of modes and exotic scales, parallel motion, extra-musicality, and evocative titles such as “Reflets dans l'eau”(“Reflections on the water”), “Brouillards” (“Mists”), etc.

The chanter (Irish: seamsúr; Scottish Gaelic: seannsair; Scots: chanter, chaunter) is the part of the bagpipe upon which the player creates the melody. It consists of a number of finger-holes, and in its simpler forms looks similar to a recorder. On more elaborate bagpipes, such as the Northumbrian bagpipes or the Uilleann pipes, it also may have a number of keys, to increase the instrument's range and/or the number of keys (in the modal sense) it can play in. Like the rest of the bagpipe, they are often decorated with a variety of substances, including metal (silver/nickel/gold/brass), bone, ivory, or plastic mountings.

Terpander (Ancient Greek: Τέρπανδρος Terpandros), of Antissa in Lesbos, was a Greek poet and citharede who lived about the first half of the 7th century BC. He was the father of Greek music and through it, of lyric poetry, although his own poetical compositions were few and in extremely simple rhythms. He simplified rules of the modes of singing of other neighboring countries and islands and formed, out of these syncopated variants, a conceptual system. Though endowed with an inventive mind, and the commencer of a new era of music, he attempted no more than to systematize the musical styles that existed in the music of Greece and Anatolia. Terpander is perhaps the earliest historically certain figure in the music of Ancient Greece.

The Phrygian mode (pronounced /ˈfrɪdʒiən/) can refer to three different musical modes: the ancient Greek tonos or harmonia, sometimes called Phrygian, formed on a particular set of octave species or scales; the medieval Phrygian mode, and the modern conception of the Phrygian mode as a diatonic scale, based on the latter.

A ricercar (/ˌriːtʃərˈkɑːr/ REE-chər-KAR, Italian: [ritʃerˈkar]) or ricercare (/ˌriːtʃərˈkɑːreɪ/ REE-chər-KAR-ay, Italian: [ritʃerˈkaːre]) is a type of late Renaissance and mostly early Baroque instrumental composition. The term ricercar derives from the Italian verb ricercare, which means "to search out; to seek"; many ricercars serve a preludial function to "search out" the key or mode of a following piece. A ricercar may explore the permutations of a given motif, and in that regard may follow the piece used as illustration. The term is also used to designate an etude or study that explores a technical device in playing an instrument, or singing.

In its most common contemporary usage, it refers to an early kind of fugue, particularly one of a serious character in which the subject uses long note values. However, the term has a considerably more varied historical usage.

In music theory, a major scale and a minor scale that have the same starting note (tonic) are called parallel keys and are said to be in a parallel relationship. For example, G major and G minor have the same tonic (G) but have different modes, so G minor is the parallel minor of G major. This relationship is different from that of relative keys, a pair of major and minor scales that share the same notes but start on different tonics (e.g., G major and E minor).

A major scale can be transformed to its parallel minor by lowering the third, sixth, and seventh scale degrees, and a minor scale can be transformed to its parallel major by raising those same scale degrees.

A jazz scale is any musical scale used in jazz. Many "jazz scales" are common scales drawn from Western European classical music, including the diatonic, whole-tone, octatonic (or diminished), and the modes of the ascending melodic minor. All of these scales were commonly used by late nineteenth and early twentieth-century composers such as Rimsky-Korsakov, Debussy, Ravel and Stravinsky, often in ways that directly anticipate jazz practice. Some jazz scales, such as the eight-note bebop scales, add additional chromatic passing tones to the familiar seven-note diatonic scales.
