Key signatures[ edit ] Key signatures define the prevailing key of the music that follows, thus avoiding the use of accidentals for many notes.
The key signature examples shown here are described as they would appear on a treble staff. Flat key signature Lowers by a semitone the pitch of notes on the corresponding line or space, and all octaves thereof, thus defining the prevailing major or minor key.
Different keys are defined by the number of flats in the key signature, starting with the leftmost, i. Quarter tones [ edit ] There is no universally accepted notation for microtonal musicwith varying systems being used depending on the situation. Below are other forms of notation: Demiflat Lowers the pitch of a note by one quarter tone.
Another notation for the demiflat is a flat with a diagonal slash through its stem. In systems where pitches are divided into intervals smaller than a quarter tone, the slashed flat represents a lower note than the reversed flat. Flat-and-a-half sesquiflat Lowers the pitch of a note by three quarter tones.
As with a demiflat, a slashed double-flat symbol is also used. Demisharp Raises the pitch of a note by one quarter tone. Sharp-and-a-half sesquisharp Raises the pitch of a note by three quarter tones. Occasionally represented with two vertical and three diagonal bars instead. A symbol with one vertical and three diagonal bars indicates a sharp with some form of alternate tuning.
Time signature Time signatures define the meter of the music. Music is "marked off" in uniform sections called bars or measures, and time signatures establish the number of beats in each.
This does not necessarily indicate which beats to emphasize, however, so a time signature that conveys information about the way the piece actually sounds is thus chosen.
Time signatures tend to suggest prevailing groupings of beats or pulses. Specific time — simple time signatures The bottom number represents the note value of the basic pulse of the music in this case the 4 represents the crotchet or quarter-note.
The top number indicates how many of these note values appear in each measure. This example announces that each measure is the equivalent length of three crotchets quarter-notes. For example, 3 4 is pronounced as "three-four time" or "three-quarter time". Specific time — compound time signatures The bottom number represents the note value of the subdivisions of the basic pulse of the music in this case the 8 represents the quaver or eighth-note.
The top number indicates how many of these subdivisions appear in each measure. Usually each beat is composed of three subdivisions. To derive the unit of the basic pulse in compound meters, double this value and add a dot, and divide the top number by 3 to determine how many of these pulses there are each measure.
This example announces that each measure is the equivalent length of two dotted crotchets dotted quarter-notes.Musical symbols are the marks and symbols, used since about the 13th century in the musical notation of musical scores, styles, and instruments to describe pitch, rhythm, tempo and, to some degree, its articulation (a composition in its fundamentals).

A statesman of the court of Theodoric the Great, he used the first. Tokyo DisneySea was the second theme park to open at the Tokyo Disney Resort and the ninth park of the twelve worldwide Disney theme parks to open.
Tokyo DisneySea was the fastest theme park in the world to reach the milestone of 10 million guests, having done so in days after its grand opening.
