Concept
In music, a tonic is the first note of a scale and serves as the central pitch around which a piece of music is organized, providing a sense of resolution and rest. It is fundamental in establishing the key of a composition and is often the starting and ending note of melodies and harmonies.
Concept
Dominance refers to the ability of an individual or group to assert influence or control over others in a social hierarchy or ecosystem. It is a dynamic status that can shift based on context, resources, and interactions within the group or environment.
Concept
The subdominant is the fourth scale degree of the diatonic scale, serving as a pivotal chord that often precedes the dominant, creating a sense of movement and anticipation in Western harmony. It plays a crucial role in establishing tonal context and is integral in the construction of various harmonic progressions, such as the plagal cadence.
Concept
A harmonic progression is a sequence of numbers where the reciprocals form an arithmetic progression. It is often used in mathematical analysis and number theory to explore relationships between numbers and their inverses.
Concept
Cadence refers to the rhythmic flow of a sequence of sounds or words, often used in music and speech to create a sense of movement and resolution. It can dictate the pace and emotional impact of a piece, influencing how an audience perceives and reacts to it.
Concept
Chord inversion involves rearranging the notes of a chord so that a note other than the root is the lowest pitch, altering the chord's texture and harmonic function without changing its fundamental identity. This technique is pivotal in creating smoother transitions between chords and enriching harmonic progressions in music composition and arrangement.
Concept
Diatonic harmony refers to the use of chords that are built from the notes of a single key, creating a sense of tonal center and coherence in music. It forms the foundation of Western music theory, allowing composers to create progressions that are both familiar and satisfying to the listener.
Concept
Chord substitution involves replacing a chord in a progression with another that has a similar harmonic function, often to add variety or complexity to the music. It relies on understanding the relationships between chords and can create new pathways for melodic and harmonic development.
Concept
Modulation is a technique used in communication systems to modify a carrier signal in order to encode information for transmission. It is essential for efficiently transmitting data over various media, allowing signals to be adapted for different frequencies and bandwidths while minimizing interference and noise.
Concept
Voice leading is the practice of writing musical parts that smoothly transition from one note to another, minimizing large leaps and maintaining the independence of individual musical lines. It is fundamental in creating harmonically rich and aesthetically pleasing compositions, especially in choral and orchestral music.
Concept
A secondary dominant is a chord that functions as the dominant of a chord other than the tonic in a given key, temporarily tonicizing that chord. It is a useful tool for creating tension and interest by introducing chromaticism and expanding harmonic progressions beyond the primary key center.
