Rest is a kind of silent symbol, also known as "silent note", which is often represented by O. In music, rest generally plays a funny role. The length of pause is basically the same as the length of note, but more O is used instead of adding timeline. Every additional O means an extra pause time equivalent to a quarter of a pause. The more o, the longer the pause time. Adding different numbers of time-reduction lines under the pause can shorten the pause time proportionally, strengthen the expressive force of the song (music), change the mood of the song (music) and make the melody show a comparative effect.
The writing methods and duration of common rests are as follows:
Adding an additional point to the right of the rest is called an additional point rest. The pause duration of the dotted rest is the same as that of the dotted note, that is, the pause duration of the original rest is increased by half.
The strong beat and weak beat of the melody circulate with a fixed sound value and are combined regularly, which is called beat. Beats are divided into single beat and double beat. Each beat of each bar consists of a complete note, that is, a simple note, called a single beat; A beat composed of dotted notes or equivalent notes in each bar is called a compound beat. The symbols used to represent different beats are called time symbols. The time signature is usually marked after key signature.
For example:
The time signature is marked in the form of a fraction. The number (numerator) on the fractional line indicates the number of beats per bar, and the number (denominator) below the fractional line indicates the duration of each note. Like 2/4? In the beat, "2" means two beats per bar, "4" means one beat of quarter note, and 2/4 means one beat of quarter note, two beats per bar. In songs and music, the relationship between note dynamics is divided by bar lines. No matter what kind of beat, the beat behind the bar line is always strong, and the beat in front of the bar line is always weak.
Third, how to understand the melody and key signature in notation?
In music works, various tones are often used in order to better express the content and emotion of the works and suit the range and performance of singing and playing.
Commonly used modes are western major mode and minor mode, both of which have seven basic tones. For example, seven tones in major mode are called "Lass" and seven tones in minor mode are called "Lass". Your teacher must have said that the relationship between mi and fa and do is semitone, and all other sounds are full-tone, and this is no exception. The classic sentence describing the main and auxiliary modes is "one machine, one machine, one machine, one machine, one machine, one machine, one machine, one machine, one machine, one machine, one machine and so on. Different modes will express different emotional colors. Major modes are usually cheerful and bright, while minor modes have sad and dim colors.
Key signature is a pitch marker used to determine the height of a song, music (or tune). In notation, key signature is a symbol used to determine the pitch position of 1(do), and its form is1= ……………. For example, when the soundtrack song is in D key, its key signature is1= d.
Any tone on the keyboard can be 1(do). After the position of the 1(do) sound on the keyboard is determined, the scale position of each sound can be found according to the relationship between the whole tone and the semitone.
