Time Signatures
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 (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. Most time signatures are either simple (the note values are grouped in pairs, like , , and ), or compound (grouped in threes, like , , and ). Less common signatures indicate complex, mixed, additive, and irrational meters. Time signature notation Most time signatures consist of two numerals, one stacked above the other: * The ''lo ...

Quarter Note
A quarter note ( AmE) or crotchet ( BrE) () 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 or crotchet. It is notated with the symbol . In some older music it was notated with symbol .''Rudiments and Theory of Music'' Associated Board of the Royal Schools of Music, London 1958. I,33 and III,25. The former section shows both forms without distinction, the latter the "old" form only. The book was the Official ABRSM theory manual in the UK up until at least 1975. The "old" form was taugh ...

Dotted Note
In Western musical notation, a dotted note is a Musical note, note with a small dot written after it. In modern practice, the first dot increases the duration (music), duration of the original note by half of its note value, value. This makes a dotted note equivalent to the original note tie (music), tied to a note of half the value – for example, a dotted half note is equivalent to a half note tied to a quarter note. Subsequent dots add progressively halved value, as shown in the example to the right. The use of dotted notes dates back at least to the 10th century, but the exact amount of lengthening a dot provides in early music contexts may vary. Mensural notation uses a dot of division to clarify ambiguities about its context-dependent interpretation of Note value, rhythmic values, sometimes alongside the dot of augmentation (music), augmentation as described above. In the gregorian chant editions of Solesmes, a dot is typically interpreted as a doubling of length (see also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compound Meter (music)
In music, metre (British 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 of music ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Time
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 (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. Most time signatures are either simple (the note values are grouped in pairs, like , , and ), or compound (grouped in threes, like , , and ).

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. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarter-note
A quarter note ( AmE) or crotchet ( BrE) () 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 REST (Representational State Transfer) is a software architectural style that was created to describe the design and guide the development of the architecture for the World Wide Web.

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 2, two as the Base (exponentiation), base and integer as the exponent. In the fast-growing hierarchy, is exactly equal to f_1^n(1). In the Hardy hierarchy, is exactly equal to H_(1). Powers of two with Sign (mathematics)#Terminology for signs, non-negative exponents are integers: , , and is two multiplication, multiplied by itself times. The first ten powers of 2 for non-negative values of are: :1, 2, 4, 8, 16 (number), 16, 32 (number), 32, 64 (number), 64, 128 (number), 128, 256 (number), 256, 512 (number), 512, ... By comparison, powers of two with negative exponents are fractions: for positive integer , is one half multiplied by itself times. Thus the first few negative powers of 2 are , , , , etc. Sometimes these are called ''inverse powers of two'' because each is the multiplicative inverse of a positive power of two.

Alla Breve
''Alla breve'' also known as cut time or cut common timeis a Meter (music), 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 language, Italian for "on the breve", originally meaning that the beat was counted on the double whole note, breve (double whole note). ''Alla breve'' is a "Meter (music)#Simple meter, simple-duple meter with a half-note pulse (music), pulse".Duckworth, William (2009). ''A Creative Approach to Music Fundamentals'', p. 38. . The note denomination that represents one beat is the minim (music), 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 Time signature#common time, "common time" refers to , which has four beats to the bar, each of a quarter note (or crotchet). Modern usage In contempora ...
