The whole evening Lensky was scattered,
It is silent, then the oars again;
But the one who Muse cherished,
Always is; Nomura eyebrow,
He sat down at the clavichord
And took them some chords...
Isn't that everyone is well familiar with these lines from "Eugene Onegin" (not once in this section you will find quotes from immortal Pushkin creations. Because his poetry is the music itself!). But have you ever think that, actually, sounded under the fingers of a young poet?
Chord - a word derived from the Italian 'accordo (agreement) means the combination of three or more musical tones of different heights, sounding simultaneously. But not every combination of sounds is a chord. If you go to the piano and two hands press the first key, it is likely that the chord does not, it will be released random combination of sounds. In the same chord sounds are arranged in a certain way: it often. so you can burn through one step from each other by intervals, which are called the third (what is the interval, look at the story about it). If the harmonies are colors that do not fit into the so-called third location, specified as packageview. When it is indifferent where the keyboard you press a key. You can extract one sound in the bass, the other in the middle of the keyboard, and the third at the top. Or one sound will play bass, second and third two flutes. Of course, the distance will be much more thirds. But this harmony is still a chord, if, after collecting all the sounds as close as possible, in one octave, you will get the location through the note.
There is another meaning of the word "chord" is a complete set of strings for any musical instrument. So, the stores sell a guitar or violin chords.
