What does it mean to underline a guitar tab, and what does it mean to have an arc on a guitar tab?

The black lines at the top are eighth notes, and the double lines are sixteenth notes.

Let's take a look. The underline is a representation of a fraction of a note.

Represents the length of the notes.

In addition to the high and low notes, of course, the notes in ** should also indicate the difference between long and short. Here is a basic term --- beat. Tempo is an important concept for denoting the length of a note.

In the notation, notes are divided into whole notes, half notes, quarter notes, sixteenth notes, thirty-second notes, etc. The most important of these notes is the quarter note, which is a basic reference measure of length, i.e. a quarter note is a beat. The concept of a beat here is a relative unit of time measurement.

If one beat is one second long, then two beats are two seconds; If one beat is set to half a second, two beats is the length of one second. Once this basic beat is set, it is relatively easy to make a symbol longer or shorter than a beat.

A horizontal line "—" is placed below the quarter note to define the length of the note.

As can be seen from the above example, there are horizontal lines marked after the notes, and there are also written below the notes, and the position of the horizontal line marks is different, and the time value of the marked note is also different. From the table, we can find a pattern, that is:

To prolong the time value of a note, add a dash to the right of a quarter note" "The horizontal line at this time is called a delay line, and the more delay lines, the longer the duration of the note (time value). Conversely, the more horizontal lines between the lower semitone and the whole plane of a note, the shorter the note time.

The arc on the guitar tablature is the "sustain line", which is used to continue the note for half a beat when the symbol is played.

As a note when sung or played, its length is equal to the sum of all these notes. In a single voice**, the line is always written in the opposite direction to the stem.

For example, a two-note sustain means that instead of playing the second note of two notes, let the first note ring until the time value of the two notes.

Other symbols

1. Extension number.

It is marked by a dot in the middle of a semicircle, and in a monophonic piece it is written on top of notes and rests, indicating that the time value of the notes or rests can be increased freely according to the style of the work and the intention of the performer.

Second, the attached point. The small dot to the right of the note head is a symbol for the value of the growing note. A note with a dot increases by one-half of the original note's value; A note with two dots increases by three-quarters of the original note's value.

Guitar tabs. The vertical line above refers to the bar line, which is drawn at the obvious segment of the ** work, and is used to indicate the end of the song The two same bar lines are called double longitudinal lines, also called double longitudinal lines. The details are as follows:

In sheet music, in front of the downbeat, the vertical line used to divide the unit of beat is called a bar line. The two bars at the end of the whole song are used to indicate the end of the whole work, and the right one is slightly thicker than the one on the left, which is called the termination line.

The bar line is a thin line perpendicular to the staff, with five lines at the top and one line at the bottom, just cutting off the staff, no matter how far the upper and lower plus lines are from the staff, the bar line cannot go beyond the staff. The beat after the bar line must be a downbeat, and there is only one downbeat for each measure, and the rest are downbeats.

There are two types of arc lines on the guitar tab, which have the following meanings:

1. Arc upward:

Indicates a coherent tone, and if there is no clear symbol, a portamento or a percussion can be used.

2. Arc downward:

Indicates the continuation of the sound, a beat needs to be played three times, the root note is played first, and then the tone is not cut, and the sound is played two times after the next beat.

The arc is a sustain line, and only the first note is played when playing, and the time value of this note is extended to the sum of the time values of the notes after the legato line, and the next note is not played. A legato is an umbrella term that refers to an upward or downward arc that connects more than two notes. But there are many forms of usage.

It's not a vertical bar, you look closely, there's a 1 on that vertical line, which means that the 1st string should be pressed by 1, and the vertical line between 1 and x means that the two notes should be played at the same time.

If there's a 1 on it, that's what the 1st floor says.

In a general guitar tab, the chord diagram is a square consisting of six vertical lines (representing the six strings of the guitar) and three or four horizontal lines (representing frets).

Below the chord diagram there is a row of six horizontal lines (representing the six strings) and some vertical lines (bar lines). The box-shaped chord diagram above represents the fingering of the left hand pressing the strings, and the diagram below with six horizontal lines represents the fingering of the right hand.

bars, but without pause.

Which vertical line, which spectrum, different vertical lines have different meanings.

I don't know which one you're talking about.

I'm stupid.

The guitar has 6 strings.

Counting from bottom to top, they are 1, 2, 3, 4, 5, 6, and which string is the vertical bar.

He's playing the X and you're going to play that string.

I don't know if you can understand it.

Is it an arrow? Refers to strumming the strings.

That's a legato mark, and if it's a staff of six lines, it's just the first one on the arc.

For example, if the two upper sweeps have arcs, only the first upper sweep will be swept up, and the upper sweep behind the arc will not need to be swept.

The extension of the previous note, which starts with the previous note and ends with the next note after the arc, is also equivalent to having only one note and doubling the duration of the ring.

Indicates a legato, which is generally a pause of 1 or 4 notes, such as a beat of 60, and a pause of about half a breath.

This is a manifestation of a six-line staff, similar to a stave.

One horizontal line represents eighth notes, and two lines represent sixteenth notes. There is only one vertical line without a horizontal line, which is a quarter note. The subtraction line functions similarly to the end of a stave.

The more endings, the shorter the tone. Only the stem has no ending, it is a four-part note.

A complete piece of music is composed of a number of fixed units, and it is very beneficial to learn music theory to distinguish these units. A complete piece consists of many notes of different time values composed of different bars, and then these bars form different phrases, different phrases form different passages, and passages form a complete piece.
