Denn Er Hat Seinen Engeln Befohlen
''Denn er hat seinen Engeln befohlen'' (''For He shall give His angels charge''), MWV B 53, is the incipit of a motet for an eight-part choir a cappella by Felix Mendelssohn. He wrote it in 1844 for the Berlin Cathedral, setting verses 11 and 12 from Psalm 91. Later, Mendelssohn made the motet with accompaniment part of his oratorio ''Elijah''. It was published in 1844, and by Breitkopf & Härtel in 1875 in the complete edition of the composer's works. History Mendelssohn composed the motet in 1844 for the choir of the Berlin Cathedral which he conducted from 1843. He dedicated it to Friedrich Wilhelm IV of Prussia, who had survived an assassination attempt shortly before. It was published by Bösenberg in Leipzig in 1844. Later, Mendelssohn made the motet with orchestral accompaniment part of his oratorio ''Elijah'', as movement 7. It appeared in 1875 in the complete edition of the composer's works by Breitkopf & Härtel. It was published in a critical edition by Bärenreit ...

Motet
In Western classical music, a motet is mainly a vocal musical composition, of highly diverse form and style, from high medieval music to the present. The motet was one of the pre-eminent polyphonic forms of Renaissance music. According to Margaret Bent, "a piece of music in several parts with words" is as precise a definition of the motet as will serve from the 13th to the late 16th century and beyond.Margaret Bent,The Late-Medieval Motet in ''Companion to Medieval & Renaissance Music'', edited by Tess Knighton and David Fallows, 114–19 (Berkeley, California: University of California Press, 1992): 114. . The late 13th-century theorist Johannes de Grocheo believed that the motet was "not to be celebrated in the presence of common people, because they do not notice its subtlety, nor are they delighted in hearing it, but in the presence of the educated and of those who are seeking out subtleties in the arts". Etymology In the early 20th century, it was generally believed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autograph
An autograph is a person's own handwriting or signature. The word ''autograph'' comes from Ancient Greek (, ''autós'', "self" and , ''gráphō'', "write"), and can mean more specifically: Gove, Philip B. (ed.), 1981. ''Webster's Third New International Dictionary'', p. 147. * a manuscript written by the author of its content. In this meaning the term ''autograph'' can often be used interchangeably with holograph. * a celebrity's handwritten signature. Autograph collecting is the activity of collecting such autographs. History What might be considered the oldest "autograph" is a Sumerian clay table from about 3100 BC which includes the name of the scribe Gar.Ama. No ancient written autographs have been found, and the earliest one known for a major historical figure is that of El Cid from 1098. Autograph manuscript "Autograph" can refer to a document transcribed entirely in the handwriting of its author, as opposed to a typeset document or one written by an amanuensis ...

Sacred Music
Religious music (also sacred music) is a type of music that is performed or composed for religious use or through religious influence. It may overlap with ritual music, which is music, sacred or not, performed or composed for or as ritual. Religious songs have been described as a source of strength, as well as a means of easing pain, improving one's mood, and assisting in the discovery of meaning in one's suffering. While style and genre vary broadly across traditions, religious groups still share a variety of musical practices and techniques. Religious music takes on many forms and varies throughout cultures. Religions such as Islam, Judaism, and Sinism demonstrate this, splitting off into different forms and styles of music that depend on varying religious practices. Religious music across cultures depicts its use of similar instruments, used in accordance to create these melodies. drums (and drumming), for example, is seen commonly in numerous religions such as Rastafari and ...

Polyphony
Polyphony ( ) is a type of musical texture consisting of two or more simultaneous lines of independent melody, as opposed to a musical texture with just one voice, monophony, or a texture with one dominant melodic voice accompanied by chords, homophony. Within the context of the Western musical tradition, the term ''polyphony'' is usually used to refer to music of the late Middle Ages and Renaissance. Baroque forms such as fugue, which might be called polyphonic, are usually described instead as contrapuntal. Also, as opposed to the ''species'' terminology of counterpoint, polyphony was generally either "pitch-against-pitch" / "point-against-point" or "sustained-pitch" in one part with melismas of varying lengths in another. In all cases the conception was probably what Margaret Bent (1999) calls "dyadic counterpoint", with each part being written generally against one other part, with all parts modified if needed in the end. This point-against-point conception is oppose ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theme (music)
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chromatism
In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point. It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength. Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing. Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image. Types There are two types of chromatic aberration: ''axial'' (''longitudinal''), and ''transverse'' (''lateral''). Axial aberration occurs when different wavelengths of light are focused at different distances from the lens (focus ''shift''). Longitudinal aberration is typical at long focal lengths. Transverse aberration occurs when different wavelengths are focused at different positions i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ter ...

Antiphon
An antiphon ( Greek ἀντίφωνον, ἀντί "opposite" and φωνή "voice") is a short chant in Christian ritual, sung as a refrain. The texts of antiphons are the Psalms. Their form was favored by St Ambrose and they feature prominently in Ambrosian chant, but they are used widely in Gregorian chant as well. They may be used during Mass, for the Introit, the Offertory or the Communion. They may also be used in the Liturgy of the Hours, typically for Lauds or Vespers. They should not be confused with Marian antiphons or processional antiphons. When a chant consists of alternating verses (usually sung by a cantor) and responds (usually sung by the congregation), a refrain is needed. The looser term antiphony is generally used for any call and response style of singing, such as the kirtan or the sea shanty and other work songs, and songs and worship in African and African-American culture. Antiphonal music is that performed by two choirs in interaction, often singing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homophony
In music, homophony (;, Greek: ὁμόφωνος, ''homóphōnos'', from ὁμός, ''homós'', "same" and φωνή, ''phōnē'', "sound, tone") is a texture in which a primary part is supported by one or more additional strands that flesh out the harmony. One melody predominates while the other parts play either single notes or an elaborate accompaniment. This differentiation of roles contrasts with equal-voice polyphony (in which similar lines move with rhythmic and melodic independence to form an even texture) and monophony (in which all parts move in unison or octaves). Historically, homophony and its differentiated roles for parts emerged in tandem with tonality, which gave distinct harmonic functions to the soprano, bass and inner voices. A homophonic texture may be homorhythmic, which means that all parts have the same rhythm. Chorale texture is another variant of homophony. The most common type of homophony is melody-dominated homophony, in which one voice, often th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allegretto
In musical terminology, tempo (Italian, 'time'; plural ''tempos'', or ''tempi'' from the Italian plural) is the speed or pace of a given piece. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats per minute (or bpm). In modern classical compositions, a "metronome mark" in beats per minute may supplement or replace the normal tempo marking, while in modern genres like electronic dance music, tempo will typically simply be stated in BPM. Tempo may be separated from articulation and meter, or these aspects may be indicated along with tempo, all contributing to the overall texture. While the ability to hold a steady tempo is a vital skill for a musical performer, tempo is changeable. Depending on the genre of a piece of music and the performers' interpretation, a piece may be played with slight tempo rubato or drastic variances. In ensembles, the tempo is often indi ...

Common Time
The time signature (also known as meter signature, metre signature, or measure signature) is a notational convention used in Western musical notation to specify how many beats (pulses) are contained in each measure (bar), and which note value is equivalent to a beat. In a music score, the time signature appears at the beginning as a time symbol or stacked numerals, such as or (read ''common time'' or ''four-four time'', respectively), immediately following the key signature (or immediately following the clef symbol if the key signature is empty). A mid-score time signature, usually immediately following a barline, indicates a change of meter. There are various types of time signatures, depending on whether the music follows regular (or symmetrical) beat patterns, including simple (e.g., and ), and compound (e.g., and ); or involves shifting beat patterns, including complex (e.g., or ), mixed (e.g., & or & ), additive (e.g., ), fractional (e.g., ), and irrat ...

Guardian Angel
A guardian angel is a type of angel that is assigned to protect and guide a particular person, group or nation. Belief in tutelary beings can be traced throughout all antiquity. The idea of angels that guard over people played a major role in Ancient Judaism. In Christianity, the hierarchy of angels was extensively developed in the 5th century by Pseudo-Dionysius the Areopagite. The theology of angels and tutelary spirits has undergone many changes since the 5th century. The belief is that guardian angels serve to protect whichever person God assigns them to. The idea of a guardian angel is central to the 15th-century book ''The Book of the Sacred Magic of Abramelin the Mage'' by Abraham of Worms, a German Cabalist. In 1897, this book was translated into English by Samuel Liddell MacGregor Mathers (1854–1918), a co-founder of the Hermetic Order of the Golden Dawn, who styled the guardian angel as the Holy Guardian Angel. Aleister Crowley (1875–1947), the founder of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
