(1) Whole note
This hollow white note is called a "whole note".
It is the eldest brother of the note family, other notes are shorter than it, and they are divided into two halves in turn.
(2) half note
(3) quarter notes
This black face note is called a "quarter note".
It's half as small as a half note, and it's equal to 1/4 of a whole note.
(4) Eighth note
This black-faced note has a tail, and it's called an "eighth note."
It's less than half a quarter note, and it's equal to 1/8 of a whole note.
(5) Sixteenth note
The black-faced note with two tails is called the "sixteenth note".
It's half as small as an eighth note, and it's equal to 1/16 of a whole note.
(6) Thirty-second note
This note with three tails is called the "thirty-second note".
It's half as short as a sixteenth note, and it's equal to 1/32 the duration of a whole note.
(7) Sixty-fourth note
The black note with four tails is called the "sixty-fourth note".
It is half of a "thirtieth note", which is equal to 1/64 of a whole note.
In the big family of notes, there are also some collateral relatives, such as the dotted note.
It's just a small round dot attached to the back of the note, so it's called a "symbol". The notes with dots are called "dotted notes".
The main function of punctuation is to simplify the score and make it easier for everyone to read the score.
Please don't underestimate this little dot, its pitch is half the length of the serious note in front of it. No matter how big the note in front of it is, this little dot has the same effect, it's very harmful. For example: the preceding is a quarter note, when the quarter note is sung for one beat, then the dotted quarter note is sung for one and a half beats; if the preceding is a whole note. When the whole note is sung in four beats, the whole dotted note is sung in six beats, and so on. Example 2:
Double punctuation is generally not used much.
What if, due to the needs of the composition, the pitch value of the sung note is longer than the dotted note? This is where the punctuation point comes in handy.
So how do you express it?
It is very simple, that is, bring a soldier behind the symbol, that is, add a symbol after the symbol. This notation is called a complex symbol.
The note marked with a doubling point is also called a doubling point note.
The algorithm for this complex point is as follows: the first dot means that the duration of the note is increased by half, and the second symbol (that is, the next dot) means that it is to increase the value of the previous one by half. time value.
The total duration of the two dots added together is three-quarters of the original duration of the note.
When transcribing notes, there are often groups of sound shapes, and there are various combinations.
In this case, they can share a hook, which is convenient for viewing the spectrum, and also saves a lot of unnecessary trouble.
The common hook of this drawing method on the score is also called "beam".
Generally, for beams drawn in this way, the direction of their stems is usually based on the note farthest from the third line, and they should be drawn thicker than the stems.
The notation method of multi-voice mainly depends on their rhythmic pattern.
When the rhythm is the same, a symbol stem can be used to express it together.
If different high and low parts are to be marked on a line of staff at the same time but the rhythm is not the same, they cannot be represented by a common "stem".
They should each use their own stems, except that the stems of the upper voice should face up, and the stems of the lower voice should face downwards. At this time, the third line is not used as the boundary.
The symbol on the score that indicates the rest of the music is called a "rest".
Rests are the nemesis of notes. As long as you see where the rests go, the notes will disappear to varying degrees, and the music will remain silent. This is the role of the rests.
But one thing must be noted:
The rests in the middle of the music usually have a special mood, and the music is not interrupted.
It can be said that "silence is better than sound at this time".
Never take the place marked with a rest as if everything is fine, rests are part of the music, they are just used to express a mood.
Various notes have corresponding rest symbols, which are the same length as the corresponding note value.
There is also a rest that expresses the rest of the whole measure. (full bar rest) They work with a variety of beats.
Note: The number of beats after the clef of a complete bar is marked, and there are several beats (including rests) within a bar, which is called a complete bar.
An incomplete measure is marked with the tempo after the clef, and there are not enough beats in the measure. This kind of measure is called an incomplete measure, and an incomplete measure is generally used as the starting beat.
More than two full-bar rests are noted like this:
See the markers for breaks above 10 bars.
Dotted rests Dotted rests are not commonly used, but we also need to recognize them.
For the rests, only the thirty-two rests and the sixty-four rests should be drawn in the fourth room, and the rests of other rests should be recorded in the third room.
