What does the 3 in the note line mean, and what does the 3 in music mean?

Triplet. It's about playing it like it's a triplet.

The most common thing that beginners are exposed to is triplets. There are many types of legato notes, which are called several legalets according to the number, such as the top of the end of the note marked with 5, which is "5 legalet", marked with 6, which is "6 legalet", marked with 3 is "3 legalet", and so on. This legato is at the position of a note of a certain value, which appears more than the prescribed note, but the time value does not change, and this growth is not an exponential increase, which produces a legato note, such as a quarter note.

There should be two eighth notes.

If you use 5 sixteenth notes.

If there are three eighth notes that occupy the space of a quarter note, it forms a "triplet", and if there are seven sixteenth notes that occupy a quarter note space, it forms a "seven". Generally, the method of marking the number of legato notes is only to write the number at the end of the note, and if it is a few legatures, write a few, and if there is a rest.

Draw lines on both sides of the number to show the relationship between the rest and the notes, but across them.

Triplet. If the value of the note is divided into three parts instead of two parts, a triplet is formed, which is represented by the number 3.

Pentatto. If the value of the note is divided into five parts instead of four parts, a pentalet is formed, which is represented by the number 5.

Septuagin. If the value of the note is divided into six parts instead of four parts, a six-tone is formed, which is represented by the number 6.

Note: Two triplets (accented on tone) and one six-tone (accented on tone) are not to be mixed.

Diplet. By dividing the dotted notes into two parts instead of three, a diplet is formed, which is represented by the number 2.

Sixteenth note triplets, according to your score, are done in half beat with the two notes in the box, the eighth note is two-thirds of the half beat, and the sixteenth note is one-third of the half beat.

Each note should have the same rhythm and the same dynamics.

This is a dotted eighth note, which should be counted in the song, depending on the beat.

For example, 4 4 beats should be counted as three-quarter beats (the eighth note itself counts half a beat, and the dots extend half of the eighth note, which adds up to three-quarter beats);

If it is 6 8 beats, count one and a half beats (one beat of the eighth note itself, and half of the eighth note extended by the dots, which adds up to one and a half beats);

One. is with quarter notes.

represented, a total of 3 beats;

Two. The first note is 3, and the hour value is one beat, and then there is a short horizontal line, called the time line, and the time value is also one beat, and this 3 - is to be sung in two beats;

Three. There is also a 0 after it, which is also a note, which is a rest.

The time value is also a beat;

Four. Write a melody in this format: the above elements are included.
