The experimentation report gives a rationale and a commentary for each process, supporting practical evidence of experiments in creating and performing, in two areas of inquiry.
实验报告为每个过程提供理据和解说，支撑在两个探究领域中进行的创作和表演实验的实践证据。
It is worth 20% at HL.
高级课程占百分之 20。
An experiment is not practice.
实验不是练习。
Practice repeats; an experiment asks what happens if one thing changes.
练习是重复；实验问的是：改变一样东西会发生什么。
Change one variable at a time, so the evidence can be attributed.
一次只改变一个变量，这样证据才能归因。
The loop: ask a question, run the trial, keep the evidence, and reach a verdict.
循环：提出问题，进行试验，保留证据，得出结论。
Keep the failed trials, because a verdict on what did not work is still a finding.
保留失败的试验，因为对无效做法的结论也是一项发现。
A fixed melody: C4, D4, E4, G4.
一段固定旋律：C4、D4、E4、G4。
The question: what does a sustained C3 below change?
问题：在下方加一个持续的 C3 会改变什么？
The trial is recorded without, then with the added part.
试验录两遍，先不加，再加。
The texture moves from monophonic to two-part and the harmony shifts, while melody and rhythm stay fixed.
织体从单声部变为二声部，和声发生变化，而旋律和节奏保持不变。
A second experiment tests accent.
第二个实验测试重音。
Eight equal notes, with the accent on every second note: listeners tap the grouping in twos.
八个等长音符，每隔一个音加重音：听众按两拍一组打拍子。
Now the accent is displaced onto every third note.
现在把重音移到每三个音一次。
Same notes, same bar lines, but listeners tap three, three, two.
音符相同，小节线相同，但听众按三、三、二打拍子。
The metre heard follows the accent, not the notation.
听到的节拍跟随重音，而不是记谱。
A work song from unfamiliar repertoire is loaded into a DAW and its tempo halved.
把一首不熟悉曲目中的劳动号子导入数字音频工作站，速度减半。
Does halving change the work the song does?
减速会改变这首歌的功能吗？
The call and response survives, but the functional rhythm loses its lift.
一领众和保留了下来，但功能性节奏失去了推动力。
Each process gets a rationale, why this experiment, written before the outcome; and a commentary, what the evidence shows, element by element.
每个过程都要有理据，即为什么做这个实验，在结果出来之前写；以及解说，即证据逐个要素显示了什么。
A rationale written after the fact reads as hindsight.
事后写的理据读起来像马后炮。
The rationale: a fixed melody isolates the added part.
理据：固定旋律把新增声部隔离出来。
The commentary: take one, monophonic and exposed; take two, two-part, with the E4 reinterpreted in a new harmony.
解说：第一遍，单声部，显得裸露；第二遍，二声部，E4 在新的和声中被重新理解。
Texture and harmony can move while melody stands still.
旋律不动时，织体和和声也可以变化。
Check yourself.
自我检测。
The loop is question, trial, evidence, verdict, with one variable changed.
循环是问题、试验、证据、结论，每次只改一个变量。
An accent on every third note is heard as three, three, two.
每三个音一次重音，听起来是三、三、二。
The report needs two areas of inquiry.
报告需要两个探究领域。
And the rationale is written before the outcome.
理据在结果出来之前写。
