Why do some composers prefer to write in compound time?

It is easier
It adds a lilt (like skipping) to the feel
it adds a stiffness (like a march) to the feel
it makes it easier for the performer to read

The main reasons why some composers prefer to write in compound time are:

1. It adds a lilt (like skipping) to the feel: Compound time signatures, such as 6/8 or 9/8, have a natural division of beats into groups of three. This gives the music a rhythmic quality that can be associated with skipping or a buoyant feel. Composers may choose compound time to evoke a light and lively atmosphere in their music.
2. It adds a stiffness (like a march) to the feel: Similarly, compound time can also provide a more regimented and marching-like quality to the music. This can be achieved by emphasizing the strong beats within each group of three, creating a structured and precise feel in the composition.
3. It makes it easier for the performer to read: Writing in compound time can make reading and interpreting the music easier for performers. The grouping of beats into threes helps musicians to mentally organize and count the rhythm more efficiently. It can enhance readability and reduce potential confusion, especially when complex or intricate rhythms are involved.

Overall, the choice of compound time signatures depends on the desired emotional and rhythmic qualities of the composition and the composer's intention.

but out of all the answer choices listed, which do you think is the best answer

Based on the options provided, the best answer would be "it adds a lilt (like skipping) to the feel." This answer captures the essence of compound time signatures, which often create a buoyant and rhythmic quality in the music, resembling a skipping motion. The other options, such as "it is easier" or "it makes it easier for the performer to read," can also be valid to some extent, but they do not fully encompass the artistic and expressive aspect that compound time can bring to a composition.
