Bar (music) in the context of "Bar-line shift"

The foot is the basic repeating rhythmic unit that forms part of a line of verse in most Indo-European traditions of poetry, including English accentual-syllabic verse and the quantitative meter of classical ancient Greek and Latin poetry. The unit is composed of syllables, and is usually two, three, or four syllables in length. The most common feet in English are the iamb, trochee, dactyl, and anapaest. The foot might be compared to a bar, or a beat divided into pulse groups, in musical notation.

A metrical foot is, in classical poetry, a combination of two or more short or long syllables in a specific order; although this "does not provide an entirely reliable standard of measurement" in heavily accented Germanic languages such as English. In these languages it is defined as a combination of one stressed and one or two unstressed syllables in a specific order.

A time signature (also known as meter signature, metre signature, and measure signature) is an indication in music notation that specifies how many note values of a particular type fit into each measure (bar). The time signature indicates the meter of a musical movement at the bar level.

In a music score the time signature appears as two stacked numerals, such as
₄ (spoken as four–four time), or a time symbol, such as (spoken as common time). It immediately follows the key signature (or if there is no key signature, the clef symbol). A mid-score time signature, usually immediately following a barline, indicates a change of meter.

Funk is a music genre that originated in African-American communities in the mid-1960s when musicians created a rhythmic, danceable new form of music through a mixture of various music genres that were popular among African-Americans in the mid-20th century. It deemphasizes melody and chord progressions and focuses on a strong rhythmic groove of a bassline played by an electric bassist and a drum part played by a percussionist, often at slower tempos than other popular music. Funk typically consists of a complex percussive groove with rhythm instruments playing interlocking grooves that create a "hypnotic" and "danceable" feel. Early funk, specifically James Brown, fused jazz and blues, and added a syncopated drum groove.

Funk originated in the mid-1960s, with James Brown's development of a signature groove that emphasized the downbeat—with a heavy emphasis on the first beat of every measure ("The One"), and the application of swung 16th notes and syncopation on all basslines, drum patterns, and guitar riffs. Rock- and psychedelia-influenced musicians Sly and the Family Stone and Parliament-Funkadelic fostered more eclectic examples of the genre beginning in the late 1960s. Other musical groups developed Brown's innovations during the 1970s and the 1980s, including Kool and the Gang, Ohio Players, Fatback Band, Jimmy Castor Bunch, Bootsy Collins, Earth, Wind & Fire, B.T. Express, Hamilton Bohannon, One Way, Lakeside, Dazz Band, The Gap Band, Slave, Aurra, Roger Troutman & Zapp, Con Funk Shun, Cameo, Bar-Kays and Chic.

In music, especially Western popular music, a bridge is a contrasting section that prepares for the return of the original material section. It adds a sense of progress within a piece of music and can be used to introduce a source of tension. In a piece in which the original material or melody is referred to as the "A" section, the bridge may be the third eight-bar phrase in a 32-bar form (the B in AABA), or may be used more loosely in verse-chorus form, or, in a compound AABA form, used as a contrast to a full AABA section.

The bridge is often used to contrast with and prepare for the return of the verse and the chorus. "The b section of the popular song chorus is often called the bridge or release ", or boredom-breaker,.

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.

In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level (or beat level). The beat is often defined as the rhythm listeners would tap their toes to when listening to a piece of music, or the numbers a musician counts while performing, though in practice this may be technically incorrect (often the first multiple level). In popular use, beat can refer to a variety of related concepts, including pulse, tempo, meter, specific rhythms, and groove.

Rhythm in music is characterized by a repeating sequence of stressed and unstressed beats (often called "strong" and "weak") and divided into bars organized by time signature and tempo indications.
