General Terms:
* Traditional Harmony: This term refers to the common practices of harmony in Western music, particularly from the Baroque to the Romantic period. This would include things like major and minor scales, chords built from those scales, and common chord progressions.
* Diatonic Harmony: This specifically refers to harmony built from the notes within a single major or minor scale. This is the foundation of "conventional keys harmony."
* Functional Harmony: This describes the way chords function within a key, creating relationships and progressions that move towards a tonic resolution. This is a key aspect of conventional harmony.
Specific Techniques:
* Cadences: These are chord progressions that create a sense of closure or resolution. Examples include the perfect authentic cadence (V-I) and the plagal cadence (IV-I).
* Modulation: This is the process of moving from one key to another. In conventional harmony, modulations often happen to related keys (like a dominant key or a relative minor) to create a sense of tension and release.
* Inversions: This refers to the different ways a chord can be arranged. In conventional harmony, different inversions of chords can create different harmonic effects.
Other Considerations:
* Key Signatures: The use of key signatures to indicate the key of a piece is a characteristic of "conventional keys harmony." This allows composers to create a sense of tonal center and stability.
* Tonal Music: This broad term encompasses any music that uses a system of keys and chords to create a sense of tonality and harmony.
Ultimately, the best way to describe the use of "conventional keys harmony" depends on the specific musical context and the particular techniques being used. But the terms and concepts listed above provide a good starting point for understanding this fundamental element of Western music.
