In music, consonance and dissonance are categorizations of simultaneous or successive sounds.Within the Western tradition, some listeners associate consonance with sweetness, pleasantness, and acceptability, and dissonance with harshness, unpleasantness, or unacceptability, although there is broad acknowledgement that this depends also on familiarity and musical expertise.

Descant is a type of medieval polyphony characterized by relatively strict note-for-note counterpoint.It is found in the organum with a plainchant tenor (i.e. low voice; vox principis), and in the conductus without the requirement of a plainchant tenor.
The emancipation of the dissonance was a concept or goal put forth by composer Arnold Schoenberg and others, including his pupil Anton Webern, who styled it The Path to the New Music. The phrase first appears in Schoenberg's 1926 essay "Opinion or Insight?". [1] It may be described as a metanarrative to justify atonality.
Lastly a double passing tone allows two dissonant passing tones in a row. The figure would consist of 4 notes moving in the same direction by step. The two notes that allow dissonance would be beat 2 and 3 or 3 and 4. The dissonant interval of a fourth would proceed into a diminished fifth and the next note would resolve at the interval of a sixth.
Resolution in Western tonal music theory is the move of a note or chord from dissonance (an unstable sound) to a consonance (a more final or stable sounding one). Dissonance, resolution, and suspense can be used to create musical interest.
Music theorist Robert Morgan has argued that a central tenet of Schenkerian thought—that only consonant triads are capable of prolongation—needlessly excludes a class of dissonant sonorities, such as diminished sevenths or a more arbitrarily defined set of pitches; Morgan claims that, starting in the 19th century, composers such as Liszt ...
Cambiata, or nota cambiata (Italian for changed note), has a number of different and related meanings in music.Generally it refers to a pattern in a homophonic or polyphonic (and usually contrapuntal) setting of a melody where a note is skipped from (typically by an interval of a third) in one direction (either going up or down in pitch) followed by the note skipped to, and then by motion in ...
Post-tonal music theory is the set of theories put forward to describe music written outside of, or 'after', the tonal system of the common practice period.It revolves around the idea of 'emancipating dissonance', that is, freeing the structure of music from the familiar harmonic patterns that are derived from natural overtones.
