The sounding of two or more tones which produce an effect of harshness or instability, and demand "resolution" to a consonance Like consonance, the concept of dissonance is dependent upon both context and the way our ears have been cultured Some intervals considered dissonant in the Medieval period were found to be consonant during the Renaissance Also, the way a dissonance is resolved (and even the way it is orchestrated) can decrease or intensify how "harsh" it sounds Intervals commonly considered dissonant in tonal music are the major and minor seconds and sevenths
The unstable, unresolved sound of an interval or chord whose constituent notes are not in simple frequency ratio relationships with each other See Section 2 14
An interaction between two or more pitches or frequencies that conflict, resulting in wobbles, beats, or rough sound In mathematical terms, they vibrate or oscillate in asymetrical relationships that cause distortion commensurate with the degree of mathematical conflict
