Music Theory

Music theory is the study of how music works. It examines the language and notation of music. It seeks to identify patterns and structures in composers' techniques across or within genres, styles, or historical periods. In a grand sense, music theory distils and analyzes the fundamental parameters or elements of music—rhythm, harmony (harmonic function), melody, structure, form, texture, etc. Broadly, music theory may include any statement, belief, or conception of or about music.A person who studies these properties is known as a music theorist. Some have applied acoustics, human physiology, and psychology to the explanation of how and why music is perceived.

Pitch

Middle C

Pitch is a subjective sensation, reflecting generally the lowness (slower wave frequency) or highness (faster wave frequency) of a sound.

Scales and modes

Pattern of whole and half steps in the Ionian mode or major scale on C .

Notes can be arranged into different scales and modes. Western music theory generally divides the octave into a series of 12 notes that might be included in a piece of music. This series of twelve notes is called a chromatic scale. In the chromatic scale, the interval between adjacent notes is called a half-step or semitone. Patterns of half and whole steps (2 half steps, or a tone) can make up a scale in that octave. The scales most commonly encountered are the seven toned major, the harmonic minor, the melodic minor, and the natural minor. Other examples of scales are the octatonic scale, and the pentatonic or five-toned scale, which is common in but not limited to folk music.

Rhythm

Metric levels: beat level shown in middle with division levels above and multiple levels below.

Rhythm is the arrangement of sounds and silences in time. Meter animates time in regular pulse groupings, called measures or bars. The time signature or meter signature specifies how many beats are in a measure, and which value of written note is counted and felt as a single beat.

Chord

A basic chord progression in C major would be "C E G." Adding the relative minor chord to it would be A minor. A more advanced chord for C major would be adding E minor. Most pop songs have a simple chord progression such as "C G Am F" another one would be "C Em Am F."

Melody

A melody is a series of tones sounding in succession. The tones of a melody are typically created with respect to pitch systems such as scales or modes. The rhythm of a melody is often based on the intonation of language, the physical rhythms of dance, or simply periodic pulsation. Melody is typically divided into phrases within a larger overarching structure. The elements of a melody are pitch, duration, dynamics, and timbre.

Harmony

IV-V-I progression in C

Harmony is the study of vertical sonorities in music. Vertical sonority refers to considering the relationships between pitches that occur together; usually this means at the same time, although harmony can also be implied by a melody that outlines a harmonic structure.

Texture

Musical texture is the overall sound of a piece of music commonly described according to the number of and relationship between parts or lines of music: monophony, heterophony, polyphony, homophony, or monody. The perceived texture of a piece may also be affected by the timbre of the instruments, the number of instruments used, and the distance between each musical line, among other things.

Expressive qualities

Expressive qualities are those elements in music that create change in music that are not related to pitch, rhythm or timbre. They include dynamics and articulation.

Dynamics

In music, the term "dynamics" normally refers to the softness or loudness of a sound or note: e.g. pianissimo or fortissimo. Until recently, most dynamics in written form were done so in Italian, but recently are sometimes written or translated into English. Another sense of the word refers to any aspect of the execution of events in a given piece; either stylistic (staccato, legato etc.) or functional (velocity) are also known as dynamics. The term is also applied to the written or printed musical notation used to indicate dynamics.

Articulation

Articulation is the manner in which the performer applies their technique to execute the sounds or notes—for example, staccato or legato. Articulation is often described rather than quantified, therefore there is room to interpret how to execute precisely each articulation.

Form or structure

Main article: Musical form

Form is a facet of music theory that explores the concept of musical syntax, on a local and global level. The syntax is often explained in terms of phrases and periods (for the local level) or sections or genre (for the global scale). Examples of common forms of Western music include the fugue, the invention, sonata-allegro, canon, strophic, theme and variations, and rondo. Popular Music often makes use of strophic form many times in conjunction with Twelve bar blues.
