What is the difference between harmony and harmonic, please?

There is no difference, both are principles of harmony and melody. Harmony advocates macro aspects, such as the matching of melodies between instruments; the matching of melodies between left and right hands on the piano; and the matching of instruments and vocals. Harmony emphasizes the matching of the main melody of the human voice, singing the main melody and melody. Two people can sing harmony with two people, three to many people or a large chorus, ranging in size!

Harmony is to sing the main melody and melody, according to the intention of the main melody, choose a different harmonic tone, not fixed which tone on the hard set of the main melody to sing, you can sing the main melody above the tone or below the tone, but also to sing a lower octave or a higher octave above the tone or below the tone, according to the need or harmony may be the same tone, or chromatic, or not a harmonic tone.

Harmony takes on the function of a Western symphony; traditional Chinese music is not much in favor of harmony, and the five tones of the tonic simply do not lend themselves to harmonic coordination. Harmony likes to cruise between chromaticism, there is no 4 there must be 7, and traditional Chinese music chromaticism used even less, if there is just accompanying role, a pass. And western music chromaticism is flooded, is not the westerners feel that the tone is only half, they find ways to find other tones to cushion or rendering, so there is the scale of the symphony. The extensive use of vocal harmonies in Beethoven's works opens up the widespread use of human harmonies. Chinese music focuses on the main theme and a mood, and the harmonies used in it are unlike anything else. Western music focuses on the sense of thickness and scale, the lack of harmony Western music is monotonous!
