Question: The four sentences (labelled 1, 2, 3, and 4) given in this question, when properly sequenced, form a coherent paragraph. Decide on the proper order for the sentences and key in this sequence of four numbers as your answer.
To the uninitiated listener, atonal music can sound like chaotic, random noise.
Atonality is a condition of music in which the constructs of the music do not ‘live’ within the confines of a particular key signature, scale, or mode.
After you realize the amount of knowledge, skill, and technical expertise required to compose or perform it, your tune may change, so to speak.
However, atonality is one of the most important movements in 20th century music.
After reading the four sentences, we know sentences 3 and 4 cannot start the sequence because they make use of conjunctions which connote that some other sentence must be preceded in this. Now because sentence 4 uses ‘however’ the sentence before that has to have a contradictory idea, this idea is present in 1, hence we have 1 and 4 as the mandatory pair in this order. Now in sentence 1 we see ‘your tune may change’, this tune is in reference to what is mentioned in sentence 1. Hence the order becomes 143. So 2 has to start the sequence.
