Final answer:
The statement is true. A crescendo in music is a directive that indicates a sequence of notes or sounds should gradually increase in volume.
Step-by-step explanation:
That is true. A crescendo in music is a directional term used to indicate that the sequence of notes or sounds should gradually increase in volume. It often appears in written musical notation as a long, stretched-out '<' symbol below the staff, guiding the performer to increase volume from a softer sound towards a louder peak. Also, it's important to note that the opposite of a crescendo is a decrescendo or diminuendo, which means to gradually decrease in volume.
