The correct answer is: b) Call-and-response patterns.
Call-and-response is a vocal form in which a phrase is sung by one person or group (the caller) and then repeated by another person or group (the responder). It is a common feature of many folk songs around the world, including those from Meghalaya.
In Meghalayan folk songs, the call-and-response pattern is often used to create a sense of community and participation. The caller will sing a phrase, and the responder will repeat it. This can be done in a number of ways, such as by having the caller sing a line and the responder sing the next line, or by having the caller sing a phrase and the responder sing the same phrase back.
The call-and-response pattern can also be used to create a sense of rhythm and movement. The caller will sing a phrase, and the responder will repeat it, but with a slight variation. This can create a sense of forward momentum and excitement.
Call-and-response is a powerful tool that can be used to create a variety of effects in folk songs. It is a common feature of Meghalayan folk songs, and it helps to create a sense of community, participation, rhythm, and movement.
The other options are incorrect because they are not common features of Meghalayan folk songs. Complex harmonies are not typically used in Meghalayan folk songs. Rhyming lyrics are not always used in Meghalayan folk songs. Electronic sampling is not used in Meghalayan folk songs.
