I think it is Musical Phrase so B.
Correct me if I am wrong.
Look at the painting by Duchamp, entitled Nude Descending a
Staircase No.2 . The repetition and shifting diagonal lines creates a sense of mechanistic motion of a nude, with
superimposed facets, similar to motion pictures. It shows elements of both the
fragmentation and synthesis of the Cubists, and the movement and dynamism of
the Futurists.
Montage: A collection or grouping of things of similar topic or containing similar things, often seen in photographs.
Those three images are a montage because two contain the same birds, and two the same species of flower. Therefore, each image is related to one another.
(I dont know the process though, I'm sorry.)
These indentations are called coffers.
Answer: Kotekan
Explanation: This is a style of playing characteristic of Balinese gamelan music, used for playing at high speed, which is possible because the notes are split between two instruments, i.e between two musicians. In this way, parts of the music that are locked together (interlocked), in the aforementioned manner are quickly played, separating the notes. The two separate parts played on the two instruments are thus combined to form a single musical line that is heard as a whole, that is, as an inseparable part, though it consists of two parts. Given that the notes have been previously split into two instruments, then the way of playing is locked again in its entirety, fast playing is possible. One note core, that is, a separable note, can be divided into two, four, and even eight notes, which are merged again into a single note core by combining the playing of multiple instruments in the aforementioned interlocking method.
