The opposition between consonance and dissonance can be made in different contexts: In acoustics or psychophysiology, the distinction may be objective.In modern times, it usually is based on the perception of harmonic partials of the sounds considered, to such an extent that the distinction really holds only in the case of harmonic sounds (i.e. sounds with harmonic partials).
The phonation of a consonant is how the vocal cords vibrate during the articulation. When the vocal cords vibrate fully, the consonant is called voiced; when they do not vibrate at all, it is voiceless. The voice onset time (VOT) indicates the timing of the phonation. Aspiration is a feature of VOT.
Dissonant intervals seem to clash. Consonant intervals seem to sound comfortable together. Commonly, perfect fourths, fifths, and octaves and all major and minor thirds and sixths are considered consonant. All others are dissonant to a greater or lesser degree. [32] Context and many other aspects can affect apparent dissonance and consonance.
Typically, in the classical common practice period a dissonant chord (chord with tension) resolves to a consonant chord. Harmonization usually sounds pleasant to the ear when there is a balance between the consonant and dissonant sounds. In simple words, that occurs when there is a balance between "tense" and "relaxed" moments.
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.
Composers started to reassess the quality of the fourth as a consonance rather than a dissonance. This would later influence the development of quartal and quintal harmony. The Tristan chord is made up of the notes F ♮, B ♮, D ♯ and G ♯ and is the first chord heard in Richard Wagner's opera Tristan und Isolde.
The consonant cambiata is not considered an idiom like the dissonant version as it does not break any rules of species counterpoint by itself. There are two consonant cambiatas in third species: One above the C.F., with 6-5-3-4; and one below, with 5-6-8-7.
