INTRODUCTION TO MUSIC THEORY

This introductory course is aimed at those wishing to learn music theory, it will go away by adding information, and any questions you have, and that can make this same page in the forum, which we will respond to all.

CONCEPT OF MUSIC

The music is, according to the traditional definition of the term, the art of organizing sound and silence, using the fundamental principles of melody, harmony and rhythm. The concept of music has evolved from its origins in ancient Greece, which brought together without distinction of poetry, music and dance as an art unit. For decades it has become more complex definition of what is and what is not music, as distinguished composers in the framework of various artistic border, have carried out works which, although could be considered music, expanding the boundaries of the definition of this art.

The music, like any artistic manifestation, is a cultural product. The purpose of this art is to provoke an aesthetic experience in listening and expressing feelings, circumstances, thoughts or ideas. The music is a stimulus that affects the individual's perceptual field, as the audio stream can fulfill varied functions (entertainment, communication, environment, etc.)...

THE PENTAGRAM

It's called the whole staff of five lines (four spaces) where musicians write.
As a staff, there are notes and rests that are represented by symbols defined value, denoting notes according to their position and password. Vertical lines are used for dividing lines called the score into bars and to facilitate reading and writing. We can see that there are figures that are above the lines and figures which are among the lines.

THE KEYS

This figure is the representation of the notes do, re, mi, fa, sol, and if the (scale DO) in the three most popular keys: The first is the key to SOL, the most widely used. The second key is the FA, which is used to write notes lower, and the third is the key of G that is used for higher grades.

The big C you see to the right of the key represents the time of the song. The letter C means that a compass is a 4 / 4 time that is more popular today Hay7 with many styles of music is time.

After that, you have the notes and their duration to start reading.

ALTERATIONS
The changes are signs that are placed to the left of the notes and change their pitch.

We can find three basic changes. Sustained rises halftone, the halftone FLAT low BECUADRO and cancels the previous alterations.

These alterations can be if you are at the beginning of staff and alter all that they represent in the score, and accidental that only affect the accompanying notes and those of your company.

FIGURES
To represent the duration of musical sounds, the notes take various forms that titles are listed.

Here are the most used in this notebook: Round, white, black, eighth note and sixteenth note.

HEIGHT AND THEIR GRAPHICAL REPRESENTATION

The height or pitch is a feature that allows us to differentiate a high-pitched sound of a grave. The height is produced by the number of vibrations per second (frequency). The sequence of sounds of different heights gives the melody.

The different heights of the sounds in music are represented by musical notes: DO - RE - MI-FA - SOL - LA - SI.

The notes are organized into scales. A scale is an organized sequence of sounds that can go upstream (low to high) or descending (from acute and severe).

THE COMP 

The Compass is what divides time into equal parts.
The numerator indicates the number of times and figures come.
The denominator indicates the kind of figures that are based on the division that can make a round that is unity.

     In this way we will have the following examples:
 
Compass 2 / 1:
                 a) is composed of two parts
                 b) Enter two figures
                 c) The figure is around 1
                 d) This means that the highest note you can include in this type of compass is a round and a minimum of notes that we can include it in many bars are the sum of which equals one round.

Compass 2 / 2:
                 a) is composed of two parts
                 b) Enter two figures
                 c) The figure is white, because a round is equivalent to two white and two figures are only 2 may be white

Compass 2 / 4:
                 a) is composed of two parts
                 b) Enter two figures
                 c) The figure is black, one white round equals 2, or 4 black so we talk about blacks.

.

Compass 3 / 2:
                 a) is composed of 3 parts
                 b) Enter 3 figures
                 c) The figure is white, because the round is divided into white and 2 indicates that the denominator is divided into two parts.

Compass 2 / 8:
                 a) It consists of 2 parts
                 b) Enter 2 figures
                 c) If we divide the round into 8 parts get quavers, or is composed of 2 quavers

Therefore there is a figure that represents a maximum time of each meter and a figurehead of the bar completely,  we could write up that appears to mark all beat.
