Invention (musical Composition)
In music, an invention is a short composition (usually for a keyboard instrument) in two-part counterpoint. Compositions in the same style as an invention but using three-part counterpoint are known as ''sinfonias.'' Some modern publishers call them "three-part inventions" to avoid confusion with symphonies. Well-known examples of inventions include the fifteen inventions that make up the first half of Johann Sebastian Bach's Inventions and Sinfonias. Inventions are usually not performed in public, but serve as exercises for keyboard students, and as pedagogical exercises for composition students. Form Inventions are similar in style to a fugue, though they are much simpler. They consist of a short exposition, a longer development, and, sometimes, a short recapitulation. The key difference is that, unlike fugues, inventions generally do not contain an answer to the subject. Two-part and three-part inventions are in contrapuntal style. Exposition In the exposition, a short motif i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention (Bach)
An invention is a unique or novel device, method, composition, idea, or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain. An inventor creates or discovers an invention. The word ''inventor'' comes from the Latin verb ''invenire'', ''invent-'', to find. Although inventing is closely associated with science and engineering, inventors are not necessarily engineers or scientists. The ideation process may be augmented by the applications of algorithms and methods from the domain collectively known as artificial intelligence . Some inventions can be patented. The system of patents was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominant (music)
In music Music is the arrangement of sound to create some combination of Musical form, form, harmony, melody, rhythm, or otherwise Musical expression, expressive content. Music is generally agreed to be a cultural universal that is present in all hum ..., the dominant is the fifth degree (music), scale degree () of the diatonic scale. It is called the ''dominant'' because it is second in importance to the first scale degree, the tonic (music), tonic. In the Solfège#Movable do solf%C3%A8ge, movable do solfège system, the dominant note is sung as "So(l)". The Triad (music), triad built on the dominant note is called the dominant chord. This chord is said to have dominant Function (music), function, which means that it creates an instability that requires the tonic (music), tonic for resolution (music), resolution. Dominant triads, Seventh chord, seventh chords, and Ninth chord, ninth chords typically have dominant function. Leading-tone triad, Leading-tone triads and Leadin ...

Queen's University Belfast
The Queen's University of Belfast, commonly known as Queen's University Belfast (; abbreviated Queen's or QUB), is a public research university in Belfast, Northern Ireland, United Kingdom. The university received its charter in 1845 as part of the Queen's University of Ireland and opened four years later, together with University of Galway (as ''Queen's College, Galway'') and University College Cork (as ''Queen's College, Cork''). Queen's offers approximately 300 academic degree programmes at various levels. The current president and Chancellor (education), vice-chancellor is Ian Greer (obstetrician), Ian Greer. The annual income of the institution for 2023–24 was £474.2 million, of which £105.2 million was from research grants and contracts, with an expenditure of £345.9 million.

Wilhelm Friedemann Bach
Wilhelm Friedemann Bach (22 November 17101 July 1784) was a German composer, organist and harpsichordist. He was the second child and eldest son of Johann Sebastian Bach and Maria Barbara Bach. Despite his acknowledged genius as an improviser and composer, his income and employment were unstable, and he died in poverty. Life Wilhelm Friedemann (hereafter Friedemann) was born in Weimar, where his father was employed as organist and chamber musician to the Duke of Saxe-Weimar. In July 1720, when Friedemann was nine, his mother Maria Barbara Bach died suddenly; Johann Sebastian Bach remarried in December 1721. J. S. Bach supervised Friedemann's musical education and career with great attention. The graded course of keyboard studies and composition that J. S. Bach provided is documented in the ''Clavier-Büchlein vor Wilhelm Friedemann Bach'' (modern spelling: ''Klavierbüchlein für Wilhelm Friedemann Bach''), with entries by both father and son. This education also included ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Francesco Antonio Bonporti
Francesco Antonio Bonporti (11 June 1672 – 19 December 1749) was an Italian priest and amateur composer. Born in Trento, he was admitted in 1691 to the ''Collegium Germanicum'' in Rome, where he studied theology. While in Rome, he also studied composition under the guidance of Giuseppe Ottavio Pitoni and possibly (since this is unconfirmed) violin with Arcangelo Corelli. Moving back to Trento, he was ordained in 1695. Bonporti's musical work consists of twelve ''opera'', published between 1696 and 1736. He influenced Johann Sebastian Bach in the development of the invention, and several of his works were mistakenly included in a set of Bach's inventions. In reality, Bach had transcribed for harpsichord four violin pieces from Bonporti's op. X (1712). He lived in Padua from 1740 until his death in 1749. Works This is a listing of his twelve ''opera'', first the Italian original, generally by Giuseppe Sala in Venice, then the French edition as published by Estienne Roger in Am ...

Musical Improvisation
Musical improvisation (also known as musical extemporization) is the creative activity of immediate ("in the moment") musical composition, which combines performance with communication of Emotion, emotions and Musical technique, instrumental technique as well as spontaneous response to other musicians. Sometimes musical ideas in improvisation are spontaneous, but may be based on Chord (music), chord changes in classical music and many other kinds of music. One definition is a "performance given extempore without planning or preparation". Another definition is to "play or sing (music) extemporaneously, by inventing Variation (music), variations on a melody or creating new melodies, rhythms and harmonies". ''Encyclopædia Britannica'' defines it as "the extemporaneous composition or free performance of a musical passage, usually in a manner conforming to certain stylistic norms but unfettered by the prescriptive features of a specific musical text." Improvisation is often done within ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Half Cadence
In Western musical theory, a cadence () is the end of a phrase in which the melody or harmony creates a sense of full or partial resolution, especially in music of the 16th century onwards.Don Michael Randel (1999). ''The Harvard Concise Dictionary of Music and Musicians'', pp. 105-106. . A harmonic cadence is a progression of two or more chords that concludes a phrase, section, or piece of music. A rhythmic cadence is a characteristic rhythmic pattern that indicates the end of a phrase. A cadence can be labeled "weak" or "strong" depending on the impression of finality it gives. While cadences are usually classified by specific chord or melodic progressions, the use of such progressions does not necessarily constitute a cadence—there must be a sense of closure, as at the end of a phrase. Harmonic rhythm plays an important part in determining where a cadence occurs. The word "cadence" sometimes slightly shifts its meaning depending on the context; for example, it ...

Circle Of Fifths
In music theory, the circle of fifths (sometimes also cycle of fifths) is a way of organizing pitches as a sequence of perfect fifths. Starting on a C, and using the standard system of tuning for Western music (12-tone equal temperament), the sequence is: C, G, D, A, E, B, F/G, C/D, G/A, D/E, A/B, F, and C. This order places the most closely related key signatures adjacent to one another. Twelve-tone equal temperament tuning divides each octave into twelve equivalent semitones, and the circle of fifths leads to a C seven octaves above the starting point. If the fifths are tuned with an exact frequency ratio of 3:2 (the system of tuning known as just intonation), this is not the case (the circle does not "close"). Definition The circle of fifths organizes pitches in a sequence of perfect fifths, generally shown as a circle with the pitches (and their corresponding keys) in clockwise order. It can be viewed in a counterclockwise direction as a circle of fourths. Harmonic progres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Relative Major
In music, 'relative keys' are the major and minor scales that have the same key signatures (enharmonically equivalent), meaning that they share all of the same notes but are arranged in a different order of whole steps and half steps. A pair of major and minor scales sharing the same key signature are said to be in a relative relationship. The relative minor of a particular major key, or the relative major of a minor key, is the key which has the same key signature but a different tonic. (This is as opposed to ''parallel'' minor or major, which shares the same tonic.) For example, F major and D minor both have one flat in their key signature at B♭; therefore, D minor is the relative minor of F major, and conversely F major is the relative major of D minor. The tonic of the relative minor is the sixth scale degree of the major scale, while the tonic of the relative major is the third degree of the minor scale. The minor key starts three semitones below its relative major; fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonically
In music, harmony is the concept of combining different sounds in order to create new, distinct musical ideas. Theories of harmony seek to describe or explain the effects created by distinct pitches or tones coinciding with one another; harmonic objects such as chords, textures and tonalities are identified, defined, and categorized in the development of these theories. Harmony is broadly understood to involve both a "vertical" dimension (frequency-space) and a "horizontal" dimension (time-space), and often overlaps with related musical concepts such as melody, timbre, and form. A particular emphasis on harmony is one of the core concepts underlying the theory and practice of Western music. The study of harmony involves the juxtaposition of individual pitches to create chords, and in turn the juxtaposition of chords to create larger chord progressions. The principles of connection that govern these structures have been the subject of centuries worth of theoretical work a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melodically
A melody (), also tune, voice, or line, is a linear succession of musical tones that the listener perceives as a single entity. In its most literal sense, a melody is a combination of Pitch (music), pitch and rhythm, while more figuratively, the term can include other musical elements such as Timbre, tonal color. It is the foreground to the background accompaniment. A line or Part (music), part need not be a foreground melody. Melodies often consist of one or more musical Phrase (music), phrases or Motif (music), motifs, and are usually repeated throughout a Musical composition, composition in various forms. Melodies may also be described by their melodic motion or the pitches or the interval (music), intervals between pitches (predominantly steps and skips, conjunct or disjunct or with further restrictions), pitch range, tension (music), tension and release, continuity and coherence, cadence (music), cadence, and shape.
