How many beats does a time signature of 6/8 divide into?

In a time signature of 6/8, the upper number indicates that there are six beats in each measure. The lower number signifies that an eighth note receives one beat. Therefore, this time signature is divided into six eighth-note beats, making option B the correct choice.

This time signature often conveys a compound feel, where one can perceive those six beats as being grouped into two sets of three. This can influence the rhythm and feel of the music, typically resulting in a flowing and lilting character. Thus, it's crucial to recognize that, while there are indeed six beats in each measure, they are usually felt in a triplet manner, affecting how musicians interpret the rhythm while performing.
