C Sad

C Sad

The correct answer is C: Sad.

A minor key in a composition usually creates a sad or melancholic mood. To understand why, we need to explain how music is formed using major and minor keys.

In music theory, major and minor keys are scales that use a specific pattern of whole and half steps. The difference between major and minor keys lies in the specific intervals between the notes. Major keys tend to sound brighter and happier, while minor keys have a darker and sadder quality.

In a minor key, the third note of the scale is a half step lower than in the corresponding major key. This smaller interval creates a minor third, which contributes to the overall emotional quality of the key. The minor third often conveys a sense of sadness, longing, or introspection.

Additionally, minor keys are commonly associated with certain harmonic progressions and melodic patterns that further enhance the emotional impact. These include the use of minor chords and dissonant intervals, such as the diminished fifth, which can add tension and drama to the composition.

While music can evoke a wide range of emotions, a composition in a minor key usually creates a sad or somber mood due to the inherent characteristics of the minor scale and the accompanying harmonies and melodies commonly used in conjunction with it.
