What is a major scale characterized by?

A major scale is characterized by a specific pattern of whole and half steps that creates a happy or bright sound. This scale follows a defined sequence: whole step, whole step, half step, whole step, whole step, whole step, half step. This structure establishes the distinct tonal quality and cheerful feeling that is often associated with major scales, making them widely used in various musical genres to convey joyous or uplifting emotions.

In contrast, other options do not accurately describe the nature of a major scale. A consistent rhythmic pattern with no fluctuating dynamics refers to rhythmic structures rather than pitch organization. A series of pitches played in reverse order aligns more with melodic sequencing rather than the defining characteristics of a scale. Lastly, a random selection of notes that lacks structure describes disorganized musical elements, which contradicts the structured and predictable nature of a major scale.
