Time Signature
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 irra ...

Alla Breve
''Alla breve'' also known as cut time or cut common timeis a musical meter notated by the time signature symbol (a C with a vertical line through it), which is the equivalent of . The term is Italian for "on the breve", originally meaning that the beat was counted on the breve. ''Alla breve'' is a "simple-duple meter with a half-note pulse".Duckworth, William (2009). ''A Creative Approach to Music Fundamentals'', p. 38. . The note denomination that represents one beat is the minim or half-note. There are two of these per bar, so that the time signature may be interpreted as "two minim beats per bar". Alternatively this is read as two beats per measure, where the half note gets the beat. The name "common time" refers to , which has four beats to the bar, each of a quarter note (or crotchet). Modern usage In contemporary use, ''alla breve'' suggests a fairly quick tempo. Thus, it is used frequently for military marches. From about 1600 to 1900, its meaning with regard to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarter Note
A quarter note (American) or crotchet ( ) (British) is a musical note played for one quarter of the duration of a whole note (or semibreve). Quarter notes are notated with a filled-in oval note head and a straight, flagless stem. The stem usually points upwards if it is below the middle line of the staff, and downwards if it is on or above the middle line. An upward stem is placed on the right side of the notehead, a downward stem is placed on the left (see image). The Unicode symbol is U+2669 (). A quarter rest (or crotchet rest) denotes a silence of the same duration as a quarter note. It typically appears as the symbol , or occasionally, as the older symbol .''Rudiments and Theory of Music'' Associated Board of the Royal Schools of Music, London 1958. I,33 and III,25.

Meter (music)
In music, metre ( Commonwealth spelling) or meter (American spelling) refers to regularly recurring patterns and accents such as bars and beats. Unlike rhythm, metric onsets are not necessarily sounded, but are nevertheless implied by the performer (or performers) and expected by the listener. A variety of systems exist throughout the world for organising and playing metrical music, such as the Indian system of '' tala'' and similar systems in Arabic and African music. Western music inherited the concept of metre from poetry, where it denotes: the number of lines in a verse; the number of syllables in each line; and the arrangement of those syllables as long or short, accented or unaccented. The first coherent system of rhythmic notation in modern Western music was based on rhythmic modes derived from the basic types of metrical unit in the quantitative metre of classical ancient Greek and Latin poetry. Later music for dances such as the pavane and galliard consisted o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Renaissance Music
Renaissance music is traditionally understood to cover European music of the 15th and 16th centuries, later than the Renaissance era as it is understood in other disciplines. Rather than starting from the early 14th-century '' ars nova'', the Trecento music was treated by musicology as a coda to Medieval music and the new era dated from the rise of triadic harmony and the spread of the ' '' contenance angloise'' ' style from Britain to the Burgundian School. A convenient watershed for its end is the adoption of basso continuo at the beginning of the Baroque period. The period may be roughly subdivided, with an early period corresponding to the career of Guillaume Du Fay (c. 1397–1474) and the cultivation of cantilena style, a middle dominated by Franco-Flemish School and the four-part textures favored by Johannes Ockeghem (1410's or 20's – 1497) and Josquin des Prez (late 1450's – 1521), and culminating during the Counter-Reformation in the florid counterpoint of Pal ...

Medieval Music
Medieval music encompasses the sacred and secular music of Western Europe during the Middle Ages, from approximately the 6th to 15th centuries. It is the first and longest major era of Western classical music and followed by the Renaissance music; the two eras comprise what musicologists generally term as early music, preceding the common practice period. Following the traditional division of the Middle Ages, medieval music can be divided into Early (500–1150), High (1000–1300), and Late (1300–1400) medieval music. Medieval music includes liturgical music used for the church, and secular music, non-religious music; solely vocal music, such as Gregorian chant and choral music (music for a group of singers), solely instrumental music, and music that uses both voices and instruments (typically with the instruments accompanying the voices). Gregorian chant was sung by monks during Catholic Mass. The Mass is a reenactment of Christ's Last Supper, intended to prov ...

Eighth-note
180px, Figure 1. An eighth note with stem extending up, an eighth note with stem extending down, and an eighth rest. 180px, Figure 2. Four eighth notes beamed together. An eighth note (American) or a quaver (British) is a musical note played for one eighth the duration of a whole note (semibreve). Its length relative to other rhythmic values is as expected—e.g., half the duration of a quarter note (crotchet), one quarter the duration of a half note (minim), and twice the value of a sixteenth note. It is the equivalent of the ''fusa'' in mensural notation. Eighth notes are notated with an oval, filled-in note head and a straight note stem with one note flag (see Figure 1). The stem is on the right of the notehead extending upwards or on the left extending downwards, depending primarily on where the notehead lies relative to the middle line of the staff. A related symbol is the eighth rest (or quaver rest), which denotes a silence for the same duration. Eighth notes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Power Of Two
A power of two is a number of the form where is an integer, that is, the result of exponentiation with number two as the base and integer as the exponent. In a context where only integers are considered, is restricted to non-negative values, so there are 1, 2, and 2 multiplied by itself a certain number of times. The first ten powers of 2 for non-negative values of are: : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, ... Because two is the base of the binary numeral system, powers of two are common in computer science. Written in binary, a power of two always has the form 100...000 or 0.00...001, just like a power of 10 in the decimal system. Computer science Two to the exponent of , written as , is the number of ways the bits in a binary word of length can be arranged. A word, interpreted as an unsigned integer, can represent values from 0 () to () inclusively. Corresponding signed integer values can be positive, negative and zero; see si ...

Irrational Meters
Irrationality is cognition, thinking, talking, or acting without inclusion of rationality. It is more specifically described as an action or opinion given through inadequate use of reason, or through emotional distress or cognitive deficiency. The term is used, usually pejoratively, to describe thinking and actions that are, or appear to be, less useful, or more illogical than other more rational alternatives. Irrational behaviors of individuals include taking offense or becoming angry about a situation that has not yet occurred, expressing emotions exaggeratedly (such as crying hysterically), maintaining unrealistic expectations, engaging in irresponsible conduct such as problem intoxication, disorganization, and falling victim to confidence tricks. People with a mental illness like schizophrenia may exhibit irrational paranoia. These more contemporary normative conceptions of what constitutes a manifestation of irrationality are difficult to demonstrate empirically because it ...
