Pentad (chord)
A pentachord in music theory may be either of two things. In pitch-class set theory, a pentachord is defined as any five pitch classes, regarded as an unordered collection . In other contexts, a pentachord may be any consecutive five-note section of a diatonic scale . A pentad is a five-note chord . Under the latter definition, a diatonic scale comprises five non-transpositionally equivalent pentachords rather than seven because the Ionian and Mixolydian pentachords and the Dorian and Aeolian pentachords are intervallically identical (CDEFG=GABCD; DEFGA=ABCDE). The name "pentachord" was also given to a musical instrument, now in disuse, built to the specifications of Sir Edward Walpole. It was demonstrated by Karl Friedrich Abel at his first public concert in London, on 5 April 1759, when it was described as "newly invented" . In the dedication to Walpole of his cello sonatas op. 3, the cellist/composer James Cervetto praised the pentachord, declaring: "I know not a mo ...

Ninth Chord CMI9 Chord
In music, a ninth is a compound interval consisting of an octave plus a second. Like the second, the interval of a ninth is classified as a dissonance in common practice tonality. Since a ninth is an octave larger than a second, its sonority level is considered less dense. Major ninth A major ninth is a compound musical interval spanning 14 semitones, or an octave plus 2 semitones. If transposed into a single octave, it becomes a major second or minor seventh. The major ninth is somewhat dissonant in sound. Transposition Some common transposing instruments sound a major ninth lower than written. These include the tenor saxophone, the bass clarinet, the baritone/euphonium when written in treble clef, and the trombone when written in treble clef ( British brass band music). When baritone/euphonium or trombone parts are written in bass clef or tenor clef they sound as written. Minor ninth A minor ninth (m9 or -9) is a compound musical interval spanning 13 semit ...

Musical Instrument
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to the beginnings of human culture. Early musical instruments may have been used for rituals, such as a horn to signal success on the hunt, or a drum in a religious ceremony. Cultures eventually developed composition and performance of melodies for entertainment. Musical instruments evolved in step with changing applications and technologies. The date and origin of the first device considered a musical instrument is disputed. The oldest object that some scholars refer to as a musical instrument, a simple flute, dates back as far as 50,000 - 60,000 years. Some consensus dates early flutes to about 40,000 years ago. However, most historians be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chords
Chord may refer to: * Chord (music), an aggregate of musical pitches sounded simultaneously ** Guitar chord a chord played on a guitar, which has a particular tuning * Chord (geometry), a line segment joining two points on a curve * Chord (astronomy), a line crossing a foreground astronomical object during an occultation which gives an indication of the object's size and/or shape * Chord (graph theory), an edge joining two nonadjacent nodes in a cycle * Chord in truss construction – an outside member of a truss, as opposed to the inner "webbed members" * Chord (aeronautics), the distance between the front and back of a wing, measured in the direction of the normal airflow.

Violoncello
The cello ( ; plural ''celli'' or ''cellos'') or violoncello ( ; ) is a bowed (sometimes plucked and occasionally hit) string instrument of the violin family. Its four strings are usually tuned in perfect fifths: from low to high, C2, G2, D3 and A3. The viola's four strings are each an octave higher. Music for the cello is generally written in the bass clef, with tenor clef, and treble clef used for higher-range passages. Played by a '' cellist'' or ''violoncellist'', it enjoys a large solo repertoire with and without accompaniment, as well as numerous concerti. As a solo instrument, the cello uses its whole range, from bass to soprano, and in chamber music such as string quartets and the orchestra's string section, it often plays the bass part, where it may be reinforced an octave lower by the double basses. Figured bass music of the Baroque-era typically assumes a cello, viola da gamba or bassoon as part of the basso continuo group alongside chordal instruments such a ...

James Cervetto
James Cervetto (8 January 1748 – 5 February 1837) was an English cellist, playing in aristocratic venues and in important concerts of the day. He was the soloist for the premiere of Haydn’s second cello concerto. Life Cervetto was born in London in 1748; his father was the cellist Giacobbe Cervetto (whose original family name was Basevi), from whom he learned to play the instrument. He soon excelled on the cello, and his first public concert took place on 23 April 1760 at the Little Theatre, Haymarket, with other musicians of similar age (including Gertrud Elisabeth Mara, at this time playing violin, later a soprano). From 1763 he played in many of the capital cities of Europe. In 1771 he joined the Queen's private orchestra, and in 1780 he became a member of Lord Abingdon's private orchestra. He was a soloist at the "Professional Concerts" from their establishment in 1783 until 1794. He was a member of the Royal Society of Musicians for 72 years. In the early part of his ...

Karl Friedrich Abel
Carl Friedrich Abel (22 December 1723 – 20 June 1787) was a German composer of the Classical period (music), Classical era. He was a renowned player of the viol, viola da gamba, and produced significant compositions for that instrument. Life Abel was born in Köthen (Anhalt), Köthen, a small German city, where his father, Christian Ferdinand Abel, had worked for years as the principal viol, viola da gamba and cello player in the court orchestra. In 1723 Abel senior became director of the orchestra, when the previous director, Johann Sebastian Bach, moved to Leipzig. The young Abel later boarded at St. Thomas School, Leipzig, where he was taught by Bach. On Bach's recommendation in 1743 he was able to join Johann Adolph Hasse's court orchestra at Dresden, where he remained for fifteen years.

Edward Walpole
Sir Edward Walpole KB PC (Ire) (1706 – 12 January 1784) was a British politician, and a younger son of Sir Robert Walpole, Prime Minister from 1721 to 1742. Early life The second son of Sir Robert Walpole, he was educated at Eton (1718) and King's College, Cambridge (1725) and studied law at Lincoln's Inn (1723), where he was called to the bar in 1727. He undertook a Grand Tour in Italy in 1730. Political career Walpole first entered Parliament as Member for Lostwithiel in a by-election on 29 April 1730, following the death of Sir Edward Knatchbull earlier that month.

Richard Walpole (son of Lord Walpole of Wolterton) replaced him. On 7 September 1737 the Duke of Devonshire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeolian Mode
The Aeolian mode is a musical mode or, in modern usage, a diatonic scale also called the natural minor scale. On the white piano keys, it is the scale that starts with A. Its ascending interval form consists of a ''key note, whole step, half step, whole step, whole step, half step, whole step, whole step.'' That means that, in A aeolian (or A minor), you would play A, move up a whole step (two piano keys) to B, move up a half step (one piano key) to C, then up a whole step to D, a whole step to E, a half step to F, a whole step to G, and a final whole step to a high A. : History The word ''Aeolian'', like the names for the other ancient Greek ''tonoi'' and ''harmoniai'', is an ethnic designation: in this case, for the inhabitants of Aeolis (Αἰολίς)—the Aeolian Islands and adjacent coastal district of Asia Minor. In the music theory of ancient Greece, it was an alternative name (used by some later writers, such as Cleonides) for what Aristoxenus called the Low Lydian '' ...

Music Theory
Music theory is the study of the practices and possibilities of music. ''The Oxford Companion to Music'' describes three interrelated uses of the term "music theory". The first is the "rudiments", that are needed to understand music notation (key signatures, time signatures, and rhythmic notation); the second is learning scholars' views on music from antiquity to the present; the third is a sub-topic of musicology that "seeks to define processes and general principles in music". The musicological approach to theory differs from music analysis "in that it takes as its starting-point not the individual work or performance but the fundamental materials from which it is built." Music theory is frequently concerned with describing how musicians and composers make music, including tuning systems and composition methods among other topics. Because of the ever-expanding conception of what constitutes music, a more inclusive definition could be the consideration of any sonic phenomena, ...

Dorian Mode
Dorian mode or Doric mode can refer to three very different but interrelated subjects: one of the Ancient Greek ''harmoniai'' (characteristic melodic behaviour, or the scale structure associated with it); one of the medieval musical modes; or—most commonly—one of the modern modal diatonic scales, corresponding to the piano keyboard's white notes from D to D, or any transposition of itself. : Greek Dorian mode The Dorian mode (properly ''harmonia'' or ''tonos'') is named after the Dorian Greeks. Applied to a whole octave, the Dorian octave species was built upon two tetrachords (four-note segments) separated by a whole tone, running from the ''hypate meson'' to the ''nete diezeugmenon''. In the enharmonic genus, the intervals in each tetrachord are quarter tone–quarter tone–major third. : In the chromatic genus, they are semitone–semitone–minor third. : In the diatonic genus, they are semitone–tone–tone. : In the diatonic genus, the sequence over the ...
