Which of the following is a characteristic of a major scale?

A major scale is characterized by a sequence of notes that typically evokes a happy or bright sound. This emotional quality is largely due to the specific pattern of whole and half steps that comprise the scale, which creates a sense of resolution and positivity often associated with cheerful music.

The interval structure of a major scale consists of a specific arrangement: whole step, whole step, half step, whole step, whole step, whole step, half step, which contributes to its uplifting sound. Musicians commonly use major scales to produce music that is joyous and celebratory, making the association with happiness strong and recognizable across various musical styles.

This aligns with the broader understanding of scales in music theory, where major scales are integral to many compositions intended to convey light or uplifting emotions, contrasting with minor scales which usually have a melancholic feel.

In contrast, the other options describe characteristics that do not apply to major scales. For instance, a sequence of notes that sounds sad aligns more with minor scales, while the presence of sharps and flats can vary widely in both major and minor contexts. The order of arrangement also does not define a major scale, as they can be played ascending or descending.
