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 are 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 inventions do not generally contain an answer to the subject in the dominant key, whereas the fugue does. Two-part and three-part inventions are in contrapuntal style. Exposition In the exposition, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invention (Bach)
An invention is a unique or novelty (patent), novel machine, 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. Due to advances in evolutionary_robotics, artificial intelligence, the term "inventor" no longer exclusively applies to an occupation (see computer_(occupation), human computers). ...

Recapitulation (music)
In music theory, the recapitulation is one of the sections of a movement written in sonata form. The recapitulation occurs after the movement's development section, and typically presents once more the musical themes from the movement's exposition. This material is most often recapitulated in the tonic key of the movement, in such a way that it reaffirms that key as the movement's home key. In some sonata form movements, the recapitulation presents a straightforward image of the movement's exposition. However, many sonata form movements, even early examples, depart from this simple procedure. Devices used by composers include incorporating a secondary development section, or varying the character of the original material, or rearranging its order, or adding new material, or omitting material altogether, or overlaying material that was kept separate in the exposition. The composer of a sonata form movement may disguise the start of the recapitulation as an extension of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Friedemann Bach
Wilhelm Friedemann Bach (22 November 17101 July 1784), the second child and eldest son of Johann Sebastian Bach and Maria Barbara Bach, was a German composer and performer. Despite his acknowledged genius as an organist, 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 (parts of) ... [...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 ...

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 emotions and instrumental technique as well as spontaneous response to other musicians. Sometimes musical ideas in improvisation are spontaneous, but may be based on 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 (or based on) a pre-existing harmonic frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harmonically
In music, harmony is the process by which individual sounds are joined together or composed into whole units or compositions. Often, the term harmony refers to simultaneously occurring frequencies, pitches ( tones, notes), or chords. However, harmony is generally understood to involve both vertical harmony (chords) and horizontal harmony (melody). Harmony is a perceptual property of music, and, along with melody, one of the building blocks of Western music. Its perception is based on consonance, a concept whose definition has changed various times throughout Western music. In a physiological approach, consonance is a continuous variable. Consonant pitch relationships are described as sounding more pleasant, euphonious, and beautiful than dissonant relationships which sound unpleasant, discordant, or rough. The study of harmony involves chords and their construction and chord progressions and the principles of connection that govern them. Counterpoint, which refers to the ...

Melodically
A melody (from Greek μελῳδία, ''melōidía'', "singing, chanting"), 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 and rhythm, while more figuratively, the term can include other musical elements such as tonal color. It is the foreground to the background accompaniment. A line or part need not be a foreground melody. Melodies often consist of one or more musical phrases or motifs, and are usually repeated throughout a composition in various forms. Melodies may also be described by their melodic motion or the pitches or the intervals between pitches (predominantly conjunct or disjunct or with further restrictions), pitch range, tension and release, continuity and coherence, cadence, and shape. Function and elements Johann Philipp Kirnberger argued: The Norwegian composer Marcus Paus has argued: Given the many and varied elements ...

Variation (music)
In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these. Variation techniques Mozart's Twelve Variations on "Ah vous dirai-je, Maman" (1785), known in the English-speaking world as "Twinkle, Twinkle, Little Star" exemplifies a number of common variation techniques. Here are the first eight bars of the theme: Melodic variation Mozart's first variation decorates and elaborates the plain melodic line: Rhythmic variation The fifth variation breaks up the steady pulse and creates syncopated off-beats: Harmonic variation The seventh variation introduces powerful new chords, which replace the simple harmonies originally implied by the theme with a prolongational series of descending fifths: Minor mode In the elaborate eighth variation, Mozart changes from the major to the parallel minor mode, while combining three techniques: count ...

Counterpoint
In music, counterpoint is the relationship between two or more musical lines (or voices) which are harmonically interdependent yet independent in rhythm and melodic contour. It has been most commonly identified in the European classical tradition, strongly developing during the Renaissance and in much of the common practice period, especially in the Baroque period. The term originates from the Latin ''punctus contra punctum'' meaning "point against point", i.e. "note against note". In Western pedagogy, counterpoint is taught through a system of species (see below). There are several different forms of counterpoint, including imitative counterpoint and free counterpoint. Imitative counterpoint involves the repetition of a main melodic idea across different vocal parts, with or without variation. Compositions written in free counterpoint often incorporate non-traditional harmonies and chords, chromaticism and dissonance. General principles The term "counterpoint" has been us ...

Countersubject
In music, a subject is the material, usually a recognizable melody, upon which part or all of a composition is based. In forms other than the fugue, this may be known as the theme. Characteristics A subject may be perceivable as a complete musical expression in itself, separate from the work in which it is found. In contrast to an idea or motif, a subject is usually a complete phrase or period. The ''Encyclopédie Fasquelle'' defines a theme (subject) as " y element, motif, or small musical piece that has given rise to some variation becomes thereby a theme". Thematic changes and processes are often structurally important, and theorists such as Rudolph Reti have created analysis from a purely thematic perspective. Fred Lerdahl describes thematic relations as "associational" and thus outside his cognitive-based generative theory's scope of analysis. In different types of music Music based on a single theme is called 'monothematic', while music based on several themes is ca ...

Tonic (music)
In music, the tonic is the first scale degree () of the diatonic scale (the first note of a scale) and the tonal center or final resolution tone that is commonly used in the final cadence in tonal (musical key-based) classical music, popular music, and traditional music. In the movable do solfège system, the tonic note is sung as ''do''. More generally, the tonic is the note upon which all other notes of a piece are hierarchically referenced. Scales are named after their tonics: for instance, the tonic of the C major scale is the note C. The triad formed on the tonic note, the tonic chord, is thus the most significant chord in these styles of music. In Roman numeral analysis, the tonic chord is typically symbolized by the Roman numeral "I" if it is major and by "i" if it is minor. These chords may also appear as seventh chords: in major, as IM7, or in minor as i7 or rarely iM7: The tonic is distinguished from the root, which is the reference note of a chord, rathe ...

Motif (music)
In music, a motif IPA: ( /moʊˈtiːf/) (also motive) is a short musical phrase, a salient recurring figure, musical fragment or succession of notes that has some special importance in or is characteristic of a composition: "The motive is the smallest structural unit possessing thematic identity". The ''Encyclopédie de la Pléiade'' regards it as a "melodic, rhythmic, or harmonic cell", whereas the 1958 ''Encyclopédie Fasquelle'' maintains that it may contain one or more cells, though it remains the smallest analyzable element or phrase within a subject. It is commonly regarded as the shortest subdivision of a theme or phrase that still maintains its identity as a musical idea. "The smallest structural unit possessing thematic identity". Grove and Larousse also agree that the motif may have harmonic, melodic and/or rhythmic aspects, Grove adding that it "is most often thought of in melodic terms, and it is this aspect of the motif that is connoted by the term 'fig ...
