The scale in the current system adopted by European music (the one which brought up our ears) consists of seven stages. Of these stable (reference) are I, III and V stage, and, respectively, II, IV, VI and VII – unstable. Any work can not end on an unstable stage. His last sounds – sounds of the tonic – create in the listener a sense of completeness.
The two most important of the mode adopted in classical music – major and minor. The color of the sound, they are very different from each other. Lad – the relationship of musical sounds of different heights, some of which are perceived by the ear as a stable, and the other – as unsustainable. Different historical periods and national musical culture gave rise to a kind of frets. Each way has a certain range of emotionally-vyrazitelnyyh funds. Determinant of major and minor chord is formed by stable steps fret. The Major between I and III stage comprises two tones, and in a minor key – a half tone. Major or minor scale, you can choose from any of the twelve steps of the scale. This range will be the sound of a well-defined key, which determines the degree of the scale I – tonic. Major scale, performed by the sound to be called in C Major and minor scales on the same note – C Minor. Key expresses a particular height of a series of sounds.
Each classical piece of music written by the composer in a certain tonality that to some extent determines the nature of the work. For example, many lyrical bardic songs are written in the key of A minor. In total there are 24 tones. All of them are now widely used by composers. The first outstanding composer, has composed a cycle of works in all keys, was Johann Sebastian Bach. They were created by the deepest in content, diverse in mood works in those keys that were previously never used. Musicians and music lovers were able to feel some unknown images arise before using them.
When the entire system of 24 tones included in musical practice, we found that some composers individual tone associated with a particular shaped area, and even color. Beethoven, for example, called the B Minor “black” tone. Rimsky-Korsakov seen in all color tone.
