question 19
which of the following represents a 2 against 3 polymeter?
r--l---r--l
b-rlr-
b--rl-r-lr
l---r--l---r

Explanation:

A 2 - against - 3 polymeter involves a simultaneous combination of a rhythmic pattern in 2 and one in 3. Without knowing the exact meaning of the letters (R, L, B) in the context of rhythm here, we assume that we are looking for a pattern that reflects the 2 - against - 3 relationship. Typically, in a 2 - against - 3 polymeter, we would have a pattern where a group of 2 events and a group of 3 events are interwoven. Analyzing the options, we need to look for a pattern that can be divided into groups of 2 and 3 in a simultaneous and contrasting way.

Answer:

No correct option provided as the meaning of the symbols (R, L, B) is not defined. If we assume R and L are beats or rhythmic events, none of the given options clearly show a 2 - against - 3 polymetric relationship in a standard and obvious way without further context.
