An augmented sixth chord is a chromatic chord used in classical music to create tension and resolve to the dominant, characterized by the interval of an augmented sixth above the bass note. It comes in three primary forms: Italian, French, and German, each with a distinctive structure and function in harmonic progression.
Chromaticism refers to the use of notes outside the standard scale or key signature in a piece of music, enhancing its emotional expressiveness and complexity. It often involves the use of half-step intervals, creating tension and color that can lead to innovative harmonic progressions and modulations.
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.
The French Augmented Sixth is a chord that creates a unique tension and resolution in music, characterized by its augmented sixth interval between the lowered sixth scale degree and the raised fourth scale degree. It is most commonly used to lead into the dominant chord, providing a dramatic and expressive harmonic movement.
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.
Dissonance resolution refers to the psychological process through which individuals reduce the discomfort experienced when holding conflicting beliefs, attitudes, or behaviors, often by altering one or more of these elements to achieve consistency. This mechanism plays a crucial role in maintaining mental well-being and coherence in one's belief system, influencing decision-making and behavior change.
Enharmonic equivalence refers to the phenomenon in music theory where two notes sound the same but are written differently, such as C♯ and D♭. This concept is essential for understanding key modulation and the construction of musical scales and chords in Western music.

The bass note is the lowest pitched note in a chord or piece of music, serving as the foundation upon which harmonies are built. It plays a crucial role in defining the chord's quality and the overall harmonic structure of a composition.
Non-diatonic chords are chords that contain notes not found in the prevailing key signature, introducing tension and color to a musical piece. They are often used to create unexpected harmonic shifts and to enrich the emotional palette of a composition.
