\n\t\t\tTOPIC; TIME SIGNATURE
\n<\/strong>Time signature consists of 2 figures written in form of fraction 2\/2 at the left side of a piece of music to indicate the tuning of the music. E.g. 2\/2, 2\/4, 3\/8, etc.
\n2 Numerator and 2 Denominator.
\nThe\u00a0time signature<\/strong>\u00a0(also known as\u00a0meter\u00a0signature<\/strong>,\u00a0meter signature<\/strong>,\u00a0or\u00a0measure signature<\/strong>) is a notational convention used in\u00a0Western\u00a0musical notation\u00a0to specify how many\u00a0beats\u00a0(pulses) are to be contained in each\u00a0bar\u00a0and which\u00a0note value\u00a0is to be given one beat. In a musical score, the time signature appears at the beginning of the piece, as a time symbol or stacked numerals, such as\u00a0\"\"\u00a0or\u00a03<\/strong>4<\/strong>\u00a0(read\u00a0common time<\/em>\u00a0and\u00a0three-four time<\/em>, respectively), immediately following the\u00a0key signature or immediately following the\u00a0clef\u00a0symbol if the key signature is empty. A mid-score time signature, usually immediately following a bar line, indicates a change of meter.
\nThere are various types of time signatures, depending on whether the music follows simple rhythms or involves unusual shifting tempos, including:\u00a0
\n\t\tSimple\u00a0(such as\u00a03<\/strong> 4 or\u00a04<\/strong>4<\/strong>),\u00a0compound\u00a0(e.g.,\u00a09 8<\/strong>\u00a0or\u00a012<\/strong><\/p>\n

\t\t\t8<\/strong>),\u00a0complex\u00a0(e.g.,\u00a05<\/strong>
\n\t\t\t4<\/strong>\u00a0or\u00a07<\/strong>8<\/strong>),\u00a0mixed\u00a0(e.g.,\u00a05<\/strong>
\n\t\t\t8<\/strong>\u00a0&\u00a03<\/strong>
\n\t\t\t8<\/strong>\u00a0or\u00a06<\/strong>
\n\t\t\t8<\/strong>\u00a0&\u00a03<\/strong>4<\/strong>),\u00a0additive\u00a0(e.g.,\u00a03+2+3<\/strong>8<\/strong>),\u00a0fractional\u00a0(e.g.,\u00a02\u00bd<\/strong>4<\/strong>), and\u00a0irrational meters\u00a0 (e.g.,\u00a03<\/strong> 10\u00a0or\u00a05<\/strong>
\n\t\t\t24<\/strong>).<\/p>\n

\u00a0 The upper figure represents the number beats in a bar while the figure below represents the value of the notes. In another way, it can be written in this form 2=2 of the notes below in the bar. I.e. 0 1

\n There are two types of time signature<\/p>\n

    \n
  1. \n
    Simple Time Signature\n<\/div>\n<\/li>\n
  2. \n
    Compound Time Signature.\n<\/div>\n

    Simple time signature is grouped into three (3)

    \nIi Simple triple time
    \nIii Simple quadruple time.

    Simple time signatures

    \"\"
    \n\t\tBasic time signatures:\u00a04<\/strong>4<\/strong>, also known as common time (\"\");\u00a02<\/strong>2<\/strong>, also known as cut time or cut-common time (\"\"); plus\u00a02<\/strong>4<\/strong>;\u00a03<\/strong>4<\/strong>; and\u00a06<\/strong>8<\/strong>
    \n\t\tSimple time signatures consist of two numerals, one stacked above the other:<\/p>\n

      \n
    • \n
      The\u00a0lower<\/em>\u00a0numeral indicates the note value that represents one beat (the\u00a0beat unit<\/em>).\n<\/div>\n<\/li>\n
    • \n
      The\u00a0upper<\/em>\u00a0numeral indicates how many such beats there are grouped together in a\u00a0bar.\n<\/div>\n<\/li>\n<\/ul>\n

      For instance,\u00a02<\/strong>4<\/strong>\u00a0means two\u00a0quarter-note\u00a0(crotchet) beats per bar\u20143<\/strong>8<\/strong>\u00a0means three\u00a0eighth-note\u00a0(quaver) beats per bar.
      \nThe most common simple time signatures are\u00a02<\/strong>4<\/strong>,\u00a03<\/strong>4<\/strong>, and\u00a04<\/strong>4<\/strong>.<\/p>\n

      Notational variations in simple time.
      \n<\/h3>\n

      The symbol\u00a0\"\"\u00a0is sometimes used for\u00a04<\/strong>4<\/strong>\u00a0time, also called common time or imperfect time. The symbol is derived from a\u00a0broken circle\u00a0used in music notation from the 14th through 16th centuries, where a full circle represented what today would be written in\u00a03<\/strong>2<\/strong>\u00a0or\u00a03<\/strong>4<\/strong>\u00a0time, and was called\u00a0tempus perfectum<\/em>\u00a0(perfect time).\u00a0The symbol\"\"\u00a0is also a carry-over from the notational practice of late-Medieval and Renaissance music, where it signified\u00a0tempus imperfect diminutum<\/em>\u00a0(diminished imperfect time)\u2014more precisely, a doubling of the speed, or\u00a0proportion duple<\/em>, in duple meter.\u00a0In modern notation, it is used in place of\u00a02<\/strong>2<\/strong>\u00a0and is called\u00a0all a brave<\/em>\u00a0or, colloquially,\u00a0cut time<\/em>\u00a0or\u00a0cut common time<\/em>.<\/p>\n

      Compound time signatures
      \n\t\t\t\t<\/h2>\n

      in compound meter, subdivisions (which are what the upper number represents in these meters) of the main beat are in three equal parts, so that a\u00a0dotted note\u00a0(half again longer than a regular note) becomes the beat unit. Compound time signatures are named as if they were simple time signatures, in which the one-third part of the beat unit is the beat, so the top number is commonly 6, 9 or 12 (multiples of 3). The lower number is most commonly an 8 (an eighth-note): as in\u00a098\u00a0or\u00a012 8.
      \n\t\t\t\t<\/h2>\n

      An example
      \n\t\t\t\t<\/h3>\n

      \n\t\t\t\t4\u00a0is a simple signature that represents three quarter notes. It has a basic feel of (Bold\u00a0denotes a stressed beat):
      \n\t\t\t\t<\/h3>\n

      One<\/strong>\u00a0two<\/em>\u00a0three<\/em>\u00a0(as in a waltz)
      \nEach quarter note might comprise two eighth-notes (quavers) giving a total of six such notes, but it still retains that three-in-a-bar feel:
      \nOne<\/strong>\u00a0and\u00a0two<\/em>\u00a0and\u00a0three<\/em>\u00a0and
      \n6<\/strong>8<\/strong>: Theoretically, this can be thought of as the same as the six-quaver form of\u00a03<\/strong>4<\/strong>\u00a0above with the only difference being that the eighth note is selected as the one-beat unit. But whereas the six quavers in\u00a03<\/strong>4<\/strong>\u00a0had been in three groups of two,\u00a06<\/strong>8<\/strong>\u00a0is practically understood to mean that they are in two groups of three, with a two-in-a-bar feel (Bold<\/strong>\u00a0denotes a stressed beat):
      \nOne<\/strong>\u00a0and a,\u00a0two<\/strong>\u00a0and a or one\u00a0two three,\u00a0four<\/strong>\u00a0five six.<\/p>\n

      Beat and time.
      \n\t\t\t\t<\/h2>\n

      Time signatures indicating two beats per bar (whether it is simple or compound) are called\u00a0duple time; those with three beats to the bar are\u00a0triple time. To the ear, a bar may seem like one singular beat. For example, a fast waltz, notated in\u00a03<\/strong>4<\/strong>\u00a0time, may be described as being\u00a0one in a bar<\/em>. Terms such as\u00a0quadruple<\/em>\u00a0(4),\u00a0quintuple<\/em> (5), and so on are also occasionally used.<\/p>\n

      \u00a0In compound time signature, each beat is dotted note which can be further sub-divided but this time, it split into three.
      \nI Compound duple time
      \nIi Compound triple time
      \nIii Compound quadruple time.<\/p>\n
