Notes and beats

The relationship between notes:

Whole note = half note × 2

Half note = quarter note ×2

Quarter note = eighth note × 2

Eighth note = sixteenth note × 2

Sixteenth note = thirty-two Part note (Because all = 2 points × 2, and two points = 4 points × 2, so all = 4 points × 4). There is no direct relationship between notes and beats. If you are given a note, you cannot know how many beats it has because there is no definition.

What is the definition?

Every song or piece of music has a beat of four-quarters (4/4) or six-eighths (6/8) after the clef. This way, we know what each note means in the score.

For example, the meaning of four-four beats is:

A quarter note is one beat, and each measure has four beats. Eighty-six beats means: one beat is an eighth note, and there are six beats per measure.

I will give some more examples to explain in detail the different relationships between notes in different situations.

For example, in the type of music with quarter notes as one beat (2/4 beat, 3/4 beat, 4/4 beat), the quarter notes that appear in these scores are all one time. Beats, other notes are calculated according to the top formula, for example: a half note is two beats, a whole note is four beats; an eighth note is one half beat (that is, half a beat), and a sixteenth note is one quarter beat . These can all be calculated according to formulas.

If it is a musical score with eighth notes as one beat (such as 3/8 beat, 6/8 beat), it will not be like the above.

At this time, the duration of the eighth note will be one beat, the duration of the quarter note will be two beats, and the duration of the half note will be four beats; the sixteenth note will be half the eighth note and half the second. One shot.

Therefore, the relationship between notes is fixed, and the durations in different scores will differ according to the definition.

Bath speed

First of all, the time unit for recording beats is generally not "seconds", but "minutes", calculated in beats/minute.

For example, if the tempo of a piece of music is 60, it means that the music has 60 beats per minute (whether it is a quarter note or an eighth note, there must be 60 beats in one minute) .

At this time, let’s connect “beats” and “seconds”. As we mentioned just now, 60 means there are 60 beats in a minute. Does a minute also have 60 seconds?

So when the speed is 60, (60 beats per minute), that is one beat per second.

When the speed is 120, there will be two beats per second.

When the speed is 180, there are three beats per second.
