What is the definition of a consonant sound?

A consonant sound in music is defined as one that creates harmony and a sense of agreement or stability between the notes being played or sung. In musical terms, consonance is typically associated with intervals and chords that sound pleasant and resolved when heard together. This sense of agreement gives listeners a feeling of rest and satisfaction.

For example, the intervals of a perfect fifth or a major third are commonly recognized as consonant in Western music. These intervals blend well to create a sound that is pleasing to the ear, contrasting with dissonant sounds, which generate tension and a need for resolution. This makes consonant sounds fundamental in establishing harmony in musical compositions.

In summary, a consonant sound reflects musical intervals that are harmonious and agreeable, providing a sense of balance and comfort in music.
