Question

question 7 of 10
the musical form that takes one idea and then changes it in some way is:

a. a theme and variations.

b. the blues.

c. a symphony.

d. song form.

Explanation:

In music, "theme and variations" is a form where a single musical idea (theme) is presented and then followed by multiple altered versions (variations) of that theme. The blues is a specific musical style with its own chord progressions and emotional expression, not defined by varying a single idea. A symphony is a large - scale musical composition with multiple movements and various musical elements, not centered around varying one idea. Song form typically has a more straightforward structure like verse - chorus, not focused on varying a single initial idea. So the musical form that takes one idea and changes it is theme and variations.

Answer:

A. a theme and variations.
