In general, impedance is the ratio of an effort variable and the flow variable that results. For this reason, the Maxwell analogy is often referred to as the impedance analogy , although the concept of impedance was not conceived until by Oliver Heaviside , some time after Maxwell's death. Specifying power conjugate variables still does not result in a unique analogy, there are multiple ways the conjugates and analogies can be specified. A new analogy was proposed by Floyd A.
Firestone in now known as the mobility analogy. In this analogy electrical impedance is made analogous to mechanical mobility the inverse of mechanical impedance. Firestone's idea was to make analogous variables that are measured across an element, and make analogous variables that flow through an element.
For instance, the across variable voltage is the analogy of velocity, and the through variable current is the analogy of force. Firestone's analogy has the advantage of preserving the topology of element connections when converting between domains. A modified form of the through and across analogy was proposed in by Horace M. Trent and is the modern understanding of through and across. The Hamiltonian variables, also called the energy variables, are those variables which when time differentiated are equal to the power conjugate variables.
The Hamiltonian variables are so called because they are the variables which usually appear in Hamiltonian mechanics. In the translational mechanical domain the Hamiltonian variables are distance displacement x and momentum p because,. There is a corresponding relationship for other analogies and sets of variables.
The integrand of a power conjugate variable with respect to a Hamiltonian variable is a measure of energy. For instance,. Has it feathers like a bird? Is it brought from famous countries. In this poem, the speaker is feeling dejected, wondering if there could be hope and morning again. The poet has used trochees, giving a strong rhythm to the poem. Notice in this first stanza , the accented syllables are emphasized. The rhyme scheme of this poem is ABAB, which means the first and the third lines rhyme, as do the second and the fourth lines.
Roethke has used three iambs, or three beats per line, giving the poem regular rhythmic flow. This poet has used anapests two unstressed syllables followed by one stressed syllable in this example. It adds to the rhythm, yet it carries a subdued effect. Freed had been given part of the writers' credit by Chess in return for his promotional activities; a common practice at the time.
In Columbia the concert ended with a near riot as Perkins began his first song as the closing act. Perkins is quoted as saying, "It was dangerous.
Lot of kids got hurt. There was a lot of rioting going on, just crazy, man! The music drove 'em insane. Roads were clogged for seven hours.
In , two black-owned record labels, one of which would become hugely successful, made their debut: Sam Cooke 's Sar, and Berry Gordy 's Motown Records. Benton had a certain warmth in his voice that attracted a wide variety of listeners, and his ballads led to comparisons with performers such as Cole , Sinatra and Tony Bennett.
The white bandleader of the Bill Black Combo, Bill Black , who had helped start Elvis Presley's career, was popular with black listeners. Ninety percent of his record sales were from black people, and his "Smokey, Part 2" rose to the 1 position on black music charts. He was once told that "a lot of those stations still think you're a black group because the sound feels funky and black.
Look at His Eyes ". By the s, the term rhythm and blues was being used as a blanket term for soul, funk , and disco. British rhythm and blues developed in the early s, largely as a response to the recordings of American artists, often brought over by African American servicemen stationed in Britain during the Cold War , or merchant seamen visiting ports such as London , Liverpool , Newcastle on Tyne and Belfast.
Most successful were the Rolling Stones, whose first eponymously titled album in largely consisted of rhythm and blues standards. They soon established themselves as the second most popular UK band after The Beatles and led a second wave of the "British Invasion" of the US pop charts.
The British Mod subculture was musically centred on rhythm and blues and later soul music, performed by artists that were not available in small London clubs around which the scene was based.

Use of polyrhythms in American music is generally traced to the influence of black culture through Dixieland and Jazz styles.
The effect of multiple soloing in these forms, often utilizing cross-rhythms comes directly from the underlying aesthetics of sub-Saharan African music. These complex rhythmic structures have been widely adopted in many current forms of western popular music.
In linguistics , rhythm or isochrony is one of the three aspects of prosody , along with stress and intonation. Languages can be categorized according to whether they are syllable-timed or stress-timed.
Speakers of syllable-timed languages such as Spanish and Cantonese put roughly equal time on each syllable; in contrast, speakers of stressed-timed languages such as English and Mandarin Chinese put roughly equal time lags between stressed syllables, with the timing of the unstressed syllables in between them being adjusted to accommodate the stress timing.
Narmour [ 31 ] describes three categories of prosodic rules which create rhythmic successions which are additive same duration repeated , cumulative short-long , or countercumulative long-short. Cumulation is associated with closure or relaxation, countercumulation with openness or tension, while additive rhythms are open-ended and repetitive.
