# 終於！ChatGPT 生出音樂了：一場 AI 音樂的冒險

累了嗎？來聽一段用 AI 做出的輕音樂吧～～

今年六月的時候，有個朋友突發奇想，問我可不可以用 GPT 為某個活動產生一段開場音樂。聽到這麼有趣的挑戰，我受不了啊～～忍不住就動手實作了起來～～～

## EarSketch

我先查了一下，發現有個教育平台叫 [EarSketch](https://earsketch.gatech.edu/earsketch2/)，透過音樂創作和混音來教授 Python 和 Javascript，其中包含了大量的音樂素材，可以讓使用者在網站上透過程式碼將素材組合成音樂片段。在網站上可以選擇不同的創作者、曲風、曲調和樂器的音樂片段來組合創作，感覺起來比較像是 DJ 的體驗網站。網站上也可以讓我們直接編輯 python script，依照自己的喜好產生音樂。可惜沒有 python 套件可以直接在本地端使用。

所以，我試著直接要求 ChatGPT 產生一段 `EarSketch` 的範例程式碼給我，但很不幸的是，ChatGPT 往往會給**錯誤的素材名稱**，導致無法正確執行。

只好自己試著在網站自己玩玩看。但是，這種事情真的很講天份，自己以為好聽的東西，別人就是聽起來怪怪的

- 我的音樂：https://earsketch.gatech.edu/earsketch2/?sharing=C9p2oaPUPySZrh0xXOFViGW32m5XSxrdTP7OlEU9pKc

而且音樂片段真的太豐富了，有四千多個，要一一聽過，並且做組合真的有點辛苦~~~
只好，開始想辦法偷懶。

## ChatGPT ABC Notation

以下嘗試使用 GPT-4 來產出音樂。

### abcjs quick editor
接著，我在網路上發現了一種稱為ABC譜的記譜方式，它使用數字和英文字母來表示音長和音階。由於我高中時學過吉他且能讀懂吉他譜，我決定在網上尋找一段和絃譜，將其以文字方式丟給 ChatGPT 轉換為 ABC 譜。我隨後將轉換後的譜貼到了[ABCjs Quick Editor](https://editor.drawthedots.com/)這個網站上，該網站能夠將ABC譜演奏出音樂，並最終產生了一段聲音：
[和弦 ABC notation](https://editor.drawthedots.com/?t=X%3A1%0AT%3AUnkown%20Title%0AM%3A4%2F4%0AL%3A1%2F4%0AK%3AG%0A%22G%22G2%20%22Am%22A2%20%7C%22Em%22E2%20%22Am%22A2%20%7C%20%22G%22G2%20%22Am%22A2%20%7C%20%22Em%22E2%20%22Am%22A2%20%7C%0A%22D7%22D2%20%22G%22G2%20%7C%22C%22C2%20%22D%22D2%20%7C%20%22Em%22E2%20%22Bm%22B2%20%7C%20%22Am%22A2%20%22D7%22D2%20%7C%7C%0A)

這段音樂雖然只是和弦的MIDI版本，但至少是一個還可以接受的開始。於是我便產生了一個想法：是否能直接獲得久石讓《天空之城》的主題曲『[君をのせて](https://www.youtube.com/watch?v=ruux1PWWYH4)』？不過，由於版權的問題，我再次被拒絕了。沒關係，我轉而請求對剛才的和弦進行改編，希望能讓音樂帶有久石讓的風格，並希望能夠有點《天空之城》的感覺。結果，我收到了一段新的音樂：
[不知道該怎麼描述的聲音](https://editor.drawthedots.com/?t=X%3A1%0AT%3AIn%20the%20Style%20of%20Hisaishi%20-%20Extended%20and%20Varied%0AM%3A4%2F4%0AL%3A1%2F8%0AK%3AC%0A%22C%22e2%20e2%20e2%20e2%20%7C%22Em%22e2%20e2%20%22A7%22f2%20f2%20%7C%22Dm%22d2%20d2%20%22Bdim%22d2%20c2%20%7C%22G7%22B2%20B2%20B2%20B2%20%7C%0A%22C%22e2%20e2%20e2%20e2%20%7C%22Am%22c2%20c2%20%22Dm%22d2%20d2%20%7C%22F%22f2%20%22E7%22e2%20%22Am%22a2%20a2%20%7C%20g2%20g2%20f2%20e2%20%7C%0A%22D7%22d2%20d2%20d2%20d2%20%7C%22G%22g2%20g2%20%22C%2Fe%22f2%20f2%20%7C%22Am%22e2%20e2%20%22F%23dim%22d2%20d2%20%7C%22B7%22B2%20A2%20g2%20g2%20%7C%0A%22Em%22g2%20g2%20g2%20g2%20%7C%22C%22e2%20%22D7%2Ff%2B%22d2%20%22G%22g2%20g2%20%7C%22E7%2Fg%23%22g2%20g2%20%22Am%22f2%20f2%20%7C%22Dm%22f2%20e2%20e2%20e2%20%7C%0A%22E7%22e2%20d2%20%22Am%22c2%20c2%20%7C%22G%2Fb%22B2%20%22C%22e2%20%22A7%22f2%20f2%20%7C%22Dm%22d2%20d2%20%22G7%22c2%20c2%20%7C%22C%22c2%20c2%20%22G7%22g2%20g2%20%7C%22C%22c4%20%7C%7C%0A)

就是一段聲音......，似乎也沒必要討論風格了XD，聽起來就是有個人很用力地彈奏鋼琴，每一下都要用力按到底的感覺～～～
試了幾次，其實都是得到這樣的聲音，看來真的無法用無腦的方式讓 ChatGPT 產出音樂。

### 讓 ChatGPT 模仿一下

ABCjs Quick Editor 的網站預設會給一首標題為 [Cooley's](https://editor.drawthedots.com/?t=X%3A%201%0AT%3A%20Cooley%27s%0AM%3A%204%2F4%0AL%3A%201%2F8%0AR%3A%20reel%0AK%3A%20Emin%0A%7C%3AD2%7CEB%7Bc%7DBA%20B2%20EB%7C~B2%20AB%20dBAG%7CFDAD%20BDAD%7CFDAD%20dAFD%7C%0AEBBA%20B2%20EB%7CB2%20AB%20defg%7Cafe%5Ec%20dBAF%7CDEFD%20E2%3A%7C%0A%7C%3Agf%7CeB%20B2%20efge%7CeB%20B2%20gedB%7CA2%20FA%20DAFA%7CA2%20FA%20defg%7C%0AeB%20B2%20eBgB%7CeB%20B2%20defg%7Cafe%5Ec%20dBAF%7CDEFD%20E2%3A%7C?t=X%3A%201%0AT%3A%20Cooley's%0AM%3A%204%2F4%0AL%3A%201%2F8%0AR%3A%20reel%0AK%3A%20Emin%0A%7C%3AD2%7CEB%7Bc%7DBA%20B2%20EB%7C~B2%20AB%20dBAG%7CFDAD%20BDAD%7CFDAD%20dAFD%7C%0AEBBA%20B2%20EB%7CB2%20AB%20defg%7Cafe%5Ec%20dBAF%7CDEFD%20E2%3A%7C%0A%7C%3Agf%7CeB%20B2%20efge%7CeB%20B2%20gedB%7CA2%20FA%20DAFA%7CA2%20FA%20defg%7C%0AeB%20B2%20eBgB%7CeB%20B2%20defg%7Cafe%5Ec%20dBAF%7CDEFD%20E2%3A%7C) 的愛爾蘭傳統舞曲（但應該是叫 [Cooley's Reel](https://www.youtube.com/watch?v=LEYMZUuFRVU)），這首曲子給我了一個靈感，既然要 ChatGPT 憑空產出音樂不容易，不如讓他模仿一下現成的樂譜，然後再加以改造，例如改成天空之城風格的 Cooley's Reel。幾經嘗試之後得到著個版本的"音樂"：

[In the Style of Hisaishi from Cooley's](https://editor.drawthedots.com/?t=X%3A2%0AT%3AIn%20the%20Style%20of%20Hisaishi%20from%20Cooley's%0AM%3A4%2F4%0AL%3A1%2F8%0AR%3Aballad%0AK%3ADmin%0A%7C%3AA2%7C%22Dm%22D2%20C2%20D4%7CF4%20%22A7%22e4%7C%22Gm%22G4%20%22Dm%22A4%7C%22Gm%22G4%20%22A7%22A4%7C%0A%22Dm%22D2%20C2%20D4%7C%22A7%22F4%20%22Dm%22a2%20a2%7C%22Gm%22b2%20a2%20%22A7%22g4%7C%22Dm%22f6%20%3A%7C%0A%7C%3Aab%7C%22Dm%22d2%20C2%20d4%7C%22Dm%22d2%20C2%20%22A7%22a2%20a2%7C%22Gm%22D4%20%22Dm%22F4%7C%22Gm%22D4%20%22A7%22a2%20a2%7C%0A%22Dm%22d2%20C2%20%22A7%22d4%7C%22Dm%22d2%20C2%20%22A7%22a2%20a2%7C%22Gm%22b2%20a2%20%22A7%22g4%7C%22Dm%22f6%20%3A%7C%0A)

### 教 ChatGPT 樂理

我拿這段像是音樂的片段請學音樂的朋友們給點意見，大多都是覺得聽起來笨重、希望輕快一點、伴奏太大聲......之類的意見。把這些意見直接要求 ChatGPT 改善，其實成效不大，只會產生一些聽起來很像的作品。稍微檢視樂譜，我發現曲子大多由四分音符和二分音符組成，所以不夠輕快。

#### 八分音符
但是，直接要求 ChatGPT 增加八分音符其實是沒有用的，ChatGPT 並不理解八分音符要怎麼用 ABC 譜呈現。所以只好當起音樂小老師教 ChatGPT 了。

#### 補滿四拍

如果眼尖的讀者應該會發現，還有一個問題，其實 ChatGPT 給的樂譜，每個小節應該都要有四拍，但實際上許多小節都不滿四拍，所以，只好提醒一下 ChatGPT 了～～

### ChatGPT 教會我的事

我覺得還是有點沈重，ChatGPT 突然給了一個，到目前為止最好的建議：改成大調～

改變曲調後，音樂的感覺確實有了顯著的變化，感覺比較輕柔～適合當作開場音樂的感覺～

[D大調](https://editor.drawthedots.com/?t=X%3A2%0AT%3AIn%20the%20Style%20of%20Castle%20in%20the%20Sky%20from%20Cooley's%20with%20Faster%20Rhythm%20and%20Light%20Accompaniment%0AM%3A4%2F4%0AL%3A1%2F8%0AR%3Areel%0AK%3AD%0AV%3A1%0A%7C%3A%22D%22A2%20AF%20D2%20D2%7C%22A%22GABc%20d2%20d2%7C%22G%22BGAF%20D2%20D2%7C%22A%22e2e2%20A2%20A2%7C%0A%22D%22F2%20AD%20d2%20d2%7C%22A%22g2g2%20A2%20A2%7C%22D%22f2%20d2%20%22A7%22cA%20A2%7C%22D%22D4%20D4%3A%7C%0A%7C%3A%22D%22dfaf%20d2%20d2%7C%22D%22dfaf%20%22A7%22a2%20A2%7C%22G%22D2%20F2%20%22D%22A2%20A2%7C%22A%22G2%20A2%20%22A7%22A2%20A2%7C%0A%22D%22f2%20AA%20%22A7%22d2%20A2%7C%22D%22dfaf%20%22A7%22a2%20e2%7C%22G%22gfef%20e2%20e2%7C%22D%22d4%20d4%3A%7C%0A%0AV%3A2%20clef%3Dbass%0A%7C%3A%22D%22D2%20D2%20D2%20D2%7C%22A%22GA%20d2%20z2%20z2%7C%22G%22G2%20B2%20z2%20z2%7C%22A%22A2%20E2%20z2%20z2%7C%0A%22D%22D2%20AD%20z2%20z2%7C%22A%22A2%20B2%20z2%20z2%7C%22D%22D2%20d2%20z2%20z2%7C%22D%22D4%20D4%3A%7C%0A%7C%3A%22D%22D2%20F2%20A2%20D2%7C%22D%22D2%20F2%20A2%20D2%7C%22G%22G2%20B2%20d2%20G2%7C%22D%22D2%20F2%20A2%20D2%7C%0A%22D%22D2%20F2%20A2%20D2%7C%22D%22D2%20F2%20A2%20D2%7C%22G%22G2%20B2%20d2%20G2%7C%22D%22D4%20D4%3A%7C%0A)

### 花音與多樂器樂譜

後來我發現上述的每一個 ABC 譜的連結都有 ABC Cheat Sheet，說明更多進階的做法。我這邊試了一下花音和多聲部，一整個驚艷，整個曲風活潑了起來。

## MusicGEN

到目前為止，對音樂不太了解的我，其實覺得好像已經可以了，但這種事情很主觀的，給不同的人聽，就會有不同的感受，有些朋友就對這個作品不置可否。好吧～～我們還有進步空間。

後來有朋友跟我提到在 Hugging Face 上有 [MusicGEN](https://huggingface.co/spaces/facebook/MusicGen) 的公開 AI 音樂生成模型，感覺值得一試。MusicGEN 可以讓使用者上傳音樂進行改編，或者直接告訴它你想要什麼風格的音樂，然後產生一段 15 秒的音樂片段。我直接上傳用 ChatGPT 最後產出的音樂，結果比想像中的好很多，它讓原本的 MIDI 變得比較豐富，增加了許多音樂元素，使其更具音樂性。

產出的作品：[MusicGen- 上傳檔案](https://drive.google.com/file/d/19SFWzuhCeOO2Abxg59R5kBKPCkDREGci/view?usp=sharing)

也可以同時也加上描述，就又會針對描述改編，下面的音樂片段，我是加了：The style of Joe Hisaishi's theme song for 'Laputa: Castle in the Sky'

產出的作品：[MusicGen- 檔案 + 描述](https://drive.google.com/file/d/1FShzhUVaP0cTvH-AXDqaq1HYgFrz8A68/view?usp=sharing)

我也嘗試了一下，只有描述的情況，一樣是The style of Joe Hisaishi's theme song for 'Laputa: Castle in the Sky'

產出的作品：[MusicGen- 只有描述](https://drive.google.com/file/d/1S52RVol_V0et2iX49_GRWtMn_5Zqh9Ek/view?usp=sharing)

老實說，這一段聽起來很酷，有種天空很寬廣，在空中360度俯瞰天空之城的感覺，中間強烈節奏之後的停頓，就很像是正要從高處往下跳的瞬間，心臟漏跳一拍，接著急速墜向大地，真的很有冒險的 feel。

嘗試使用不同的工具和方法來製作音樂，對於我來說是一個很有趣的過程，現階段利用 AI 產生音樂，其實還是需要一點音樂相關知識，無法完全無腦產生。不過，各種 AI 模型都在光速成長，說不定過一陣子，也會有超強的 AI 模型可以讓人***無腦***生成音樂了。

## 追加內容：ChatGPT Plugin for Music

ChatGPT 有很多音樂相關的 plugin 可以用，以下挑兩個跟產生音樂有關的 Plugin 稍微說明一下：

- ABC Music Notation：
- 可以直接將 ABC 譜轉換成 MIDI ，並且提供 URL 下載。
- Music：
- 可以用這個套件生成音樂，生成的效果其實還不錯，但是結尾的感覺不太完整。
- 生成音樂後，會提供網址可以線上聆聽。
- 範例：[Sky Castle Theme – A Full Narrative](https://praison.ai/kui-mingchen/music/sky-castle-theme-a-full-narrative/)
