The Chord Track is a special global track designed for creating and playing back chord progressions. It is a permanent part of your project, fixed at the top of the track list. The track has its own built-in piano sound, so you can hear the chords you create. You can control its playback with its dedicated Mute and Volume controls on the track header and [mixer](/project/mixing/mixer.md). To show or hide the Chord Track, click the Chord Track button in the track list header. ## Create Chords On the Chord Track, double-click on the grid where you want your progression to start. This will create a new chord clip, pre-filled with four default chords. ### Edit Chords * Select a chord within the clip to edit it. The Chord Editor will appear at the bottom. * In the editor, you can choose a root note and the chord quality (e.g., Major, minor, 7th). * To set a different bass note (inversion), click the "Bass" button and select a new bass note from the keyboard display. ### Adjust and Add Chords * Drag the right boundary of any chord to change its duration. * Click the + button that appears when you hover between or after chords to insert a new chord. * To make the entire chord progression longer, simply drag the right edge of the chord clip itself. ## Chord Loop Once you have created a chord progression you like, you can easily loop it. * Click the Loop + button located at the top-right corner of the chord clip. This will create the first loop of your progression. * After the first loop is created, you can simply drag the right boundary of the last looped section to extend the loops further across your timeline. ## Use Chord Progression As Background The Chord Track can serve as a powerful compositional guide by displaying its harmony in the background of the Piano Roll. This helps you write melodies and basslines that are in key with your chords. When editing notes, locate the Scale Mode setting in the Piano Roll toolbar. Switch the mode from "Scale" to "Chord". Once enabled, the notes of the current chord from the Chord Track will be highlighted on the Piano Roll grid. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.acestudio.ai/project/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.
