# 和弦轨
和弦轨提供了用于创建和弦进行的全局工具。
和弦轨是一条专用的全局轨道，专为创建和播放和弦进行而设计。它是工程的永久组成部分，固定显示在轨道列表顶部。
该轨道自带内置钢琴音色，因此你可以听到自己创建的和弦。你可以通过轨道标题栏上的专用静音和音量控制来控制其回放， [混音器](/docs/product-wiki-zh/gong-cheng/mixing/mixer.md).
要显示或隐藏和弦轨，请点击轨道列表标题栏中的和弦轨按钮。
## 创建和弦
在和弦轨上，双击你希望和弦进行开始的位置网格。这将创建一个新的和弦片段，并预置四个默认和弦。
### 编辑和弦
* 选中片段中的某个和弦即可进行编辑。和弦编辑窗将显示在底部。
* 在编辑窗中，你可以选择根音以及和弦性质（例如：大调、小调、七和弦）。
* 要设置不同的贝斯音（转位），请点击“贝斯”按钮，并从键盘显示中选择新的贝斯音。
### 调整和添加和弦
* 拖动任意和弦的右边界即可更改其音符时长。
* 点击 + 当你将鼠标悬停在和弦之间或和弦之后时出现的按钮，用于插入新和弦。
* 要让整段和弦进行更长，只需拖动和弦片段本身的右边缘。
## 和弦循环段
一旦你创建了满意的和弦进行，就可以轻松将其循环。
* 点击循环段 + 按钮，它位于和弦片段的右上角。这将创建你的和弦进行的第一个循环段。
* 创建第一个循环段后，你只需拖动最后一个循环区段的右边界，即可将循环段进一步延伸到整个时间线。
## 将和弦进行用作背景
和弦轨可作为强大的作曲参考，通过在钢琴卷帘窗的背景中显示其和声，帮助你写出与和弦同调的旋律和贝斯线。
编辑音符时，请在钢琴卷帘窗工具栏中找到音阶模式设置。将模式从“音阶”切换为“和弦”。
启用后，和弦轨中当前和弦的音符会在钢琴卷帘窗网格中高亮显示。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.acestudio.ai/docs/product-wiki-zh/gong-cheng/arrangement-in-canvas/chord-track.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
