A brief overview of the music theory
Great Greek philosopher and mathematician Plato once said, “Music is a moral law. It gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything.”
Music theory is the study of the theoretical elements of music. Music involves sound, pitch, melody, rhythm, notation and harmony. Music theory is the study of these elements of music. It is an act of contemplation of music.
Pitch is a subjective sensation. It is the level of a tone. The higher the frequency of vibration, the higher the pitch. Likewise the lower the frequency of vibration, the lower the pitch. The difference in frequency between two pitches is known as interval.
Rhythm is a strong, regular, repeated pattern of sound. It is created by the sequential arrangement of sounds and silences. Meter measures music in regular pulse groupings. Playing simultaneous rhythms in more than one time signature is called polymeter.
Melody is a prominent aspect in music. It is a rhythmically organized sequence of single tones so related to one another as to make up a particular phrase. Pitch, rhythm, duration and tempo are the basic elements of melody.
A chord is a group of notes (three or more) sounded together, as a basis of harmony. Chords are mostly used in popular music. Chord structure provides strength to the melody.
Also known as tone color, timbre is the principal phenomenon that enables you to distinguish one musical instrument from another when both play at the same volume and pitch. It is determined by the envelop of the sound and the relative balance of overtones produced by a given instrument due to its construction.
Texture is one of the basic elements of music. It is the way the rhythmic, melodic and harmonic materials are combined in a composition. It is the overall sound of a composition.
In music theory, harmony is the study of vertical sonorities in music. Harmony is analyzed through a Roman numeral system. Roman numerals are used to identify chords based on their scalar roots. In Western music of the Common Practice Era, harmonies are generally tertian.
Musical notation is the symbolic representation of music. There are many systems of music notation.
Music is a very interesting subject. Many great personalities like Aristotle, Shoenberg and Rameau were music theorists.
