Question

select the correct answer.
which statement is true about a scale?
a. a scale consists of twelve notes.
b. scale is part of tone color.
c. a scale consists of five intervals.
d. a scale is a series of notes arranged in ascending or descending pitch.

Explanation:

• Option A is incorrect: While the chromatic scale has 12 notes, many scales (like major/minor) have 7 notes, so this is not a universal truth.
• Option B is incorrect: Tone color (timbre) refers to the quality of sound, unrelated to scales.
• Option C is incorrect: A 7-note scale has 6 intervals, so this is not accurate.
• Option D is correct: This is the core, universal definition of a musical scale.

Answer:

D. A scale is a series of notes arranged in ascending or descending pitch.
