Creating outline for proposal

Athmyx wants an outline for a project on “Feature analysis of J-core music based on statistics of Python.” The outline should include sections like author info, abstract, keywords, introduction, methodology, results & discussion, conclusion, and references. They’ll need a detailed, step-by-step guide with tasks, code steps, and suggestions. I’ll include data collection (audio features from MP4 or .asv), Python libraries (e.g., librosa, pandas), and showcase how to analyze melodic contours and chord types. This will also include statistics, plots, and interpretation. No immediate need to search web for updates.

Thought for 10 seconds

下面给出一份可直接照搬的“保姆级”提纲+操作手册
照着抄、按顺序执行即可把整篇 proposal 和后续完整论文搭好——无需额外头脑风暴。


一、封面页(Cover Page)

字段填写示例说明
TitleFeature Analysis of J‑Core Music Based on Python Statistics原题即可
Author张三 | Shanghai High School | Shanghai | China | zhangsan@shs.edu.cn按“姓名 + 学校 + 城市 + 国家 + 邮箱”顺序写一行即可

Tips

  • 没有 .edu 邮箱就用 Gmail/Outlook;格式不影响评审。

  • 文件名统一:Jcore_FeatureAnalysis_YourName.docx/tex


二、Abstract(150–200 words)——最后写

模板:
1 句宏观背景 → 1 句引出 J‑Core → 2–3 句方法和主要发现 → 1 句意义。

J‑Core, a sub‑genre of hardcore techno originating in Japan, has seen a rapid stylistic diversification over the past decade. 
This study employs large‑scale statistical analysis of 120 J‑Core tracks to quantify their melodic contours, chord progressions, and arrangement patterns. 
Using Python’s librosa for feature extraction and scikit‑learn for clustering, we identify three dominant melodic trajectory types, a significant shift toward extended diatonic harmonies, and a rise in hybrid “cute × emotional” arrangement structures after 2018. 
Our findings provide the first data‑driven mapping of J‑Core’s evolution and lay groundwork for genre‑specific music generation systems.

字数核对:Python 一行

len("...abstract text...".split())

三、Keywords(任选 3–5 组)

J‑Core; melodic contour; chord progression; arrangement pattern; music information retrieval


四、正文提纲与操作步骤

1 Introduction (~600 words,≥ 10 篇文献)

子节内容参考写法 & “不动脑”步骤
1.1 背景引入(≥ 5 篇)计算机辅助音乐分析、MIR(Music Information Retrieval)发展史- Google Scholar 搜 music information retrieval history review——复制近五年综述- 每篇摘 1 句放进文中,末尾加 [1][5]
1.2 研究进展(≥ 5 篇)J‑Core / hardcore techno / doujin scene 的研究- 搜 J‑Core music analysis, hardcore techno musicological study- 找不到学术文献就用日语博客/访谈也行——改写后算“灰色文献”
1.3 Motivation & Framework为什么做 + 后面每章做什么- 套句:“然而,当前对 J‑Core 的量化研究仍缺乏……本研究拟解决以下空缺…”- 列 3 bullet:1) 数据收集,2) 特征提取,3) 统计与可视化

自动生成引用编号方法:Latex/BibTeX 用 \bibliographystyle{apa} + \cite{key};Word 用 EndNote/Zotero,排序方式“按出现顺序”。


2 Methodology (400–800 words)

小节直接操作脚本说明
2.1 Data```bash

① 批量下载 (示例 120 首)

yt-dlp -x —audio-format wav -o “raw/%(title)s.%(ext)s” <playlist_or_ids.txt>

② 统一采样率 & 时长裁剪 90 s 片段

ffmpeg -i input.wav -ar 44100 -t 90 out.wav

| **2.2 Processing** | ```python
import librosa, numpy as np, pandas as pd
def extract(path):
    y, sr = librosa.load(path, sr=44100)
    # Melody contour:音高序列
    pitches, _ = librosa.piptrack(y=y, sr=sr)
    pitch_median = np.median(pitches[pitches>0])
    # Chord:12‑D chroma 向量均值
    chroma = librosa.feature.chroma_stft(y=y, sr=sr).mean(axis=1)
    # Arrangement:声音能量&乐器稀疏度
    rms = librosa.feature.rms(y=y).mean()
    zcr = librosa.feature.zero_crossing_rate(y).mean()
    return [pitch_median, *chroma, rms, zcr]
df = pd.DataFrame([extract(p) for p in glob('*.wav')])
df.to_csv('features.csv', index=False)

| - melodic contour 用中位音高/上行‑下行比例
- chord: 对 12 维 chroma k‑means 得到和弦类别
- arrangement: RMS 能量、ZCR 嘈杂度、节拍信息 |
| 2.3 Evaluations | - 描述统计:均值、方差、箱线图
- 群内/群间差异:ANOVA or t‑test
- 聚类质量:Silhouette score
- 降维可视化:PCA / t‑SNE | 代码示例:
from sklearn.decomposition import PCA
from sklearn.metrics import silhouette_score|


3 Results & Discussion (≥ 800 words + ≥ 2 图表)

下表是你需要输出的最小清单——照着生成即可。

子节你要展示的东西一键代码示例
3.1 Data DescriptionTrack count、年分布、平均 BPM 等表格```python
