Purpose of This Website
ChordProgressionMaker.com is a free, browser-based music theory tool and educational resource for generating chord progressions based on functional harmony rules and learning about tonal chord relationships. The site is operated by Emily Sanders, music theory educator and harmony researcher.
By accessing or using any page or tool on ChordProgressionMaker.com, you agree to be bound by these Terms and Conditions. If you do not agree to these terms, please do not use this site.
These terms apply to all visitors and users of ChordProgressionMaker.com, regardless of how you access the site or which device you use.
Use of the Chord Progression Maker
How the tool works The Chord Progression Maker requires no microphone permission, accepts no audio file uploads, and makes no server requests for tool output. All chord generation calculations are performed locally in your browser using JavaScript. No personal data of any kind is transmitted as part of using this tool. Full details are documented on the Data Security page.
Permitted use You may use the Chord Progression Maker and all content on ChordProgressionMaker.com for personal, educational, and professional reference purposes. You may share links to pages on this site freely. You may use generated chord progressions in your own compositions, arrangements, and creative work without restriction — the generated progressions are based on documented music theory rules that are in the public domain.
Prohibited use You may not:
- Scrape, copy, reproduce, or republish the written content of this site without written permission from Emily Sanders
- Use automated tools to access the site in a manner that places unreasonable load on the server
- Attempt to interfere with, disable, or circumvent any security feature of this site
- Misrepresent the source of this site’s written content or present it as your own work
- Use this site in any way that violates applicable local, national, or international law
Tool Accuracy and Limitations
The Chord Progression Maker generates chord progressions that are mathematically correct according to diatonic harmony theory. The calculations are exact within the diatonic system for all 24 major and natural minor keys.
However, correctness within the diatonic theory system does not guarantee musical effectiveness in a specific creative context. Genre conventions, voicing, harmonic rhythm, melodic content, and subjective listener response all determine whether a progression works for a specific purpose. The tool is provided as an educational and creative reference resource — not as a substitute for compositional judgment.
Known limitations — including the tool’s restriction to diatonic chord output, the absence of voice leading specification, and the contextual nature of enharmonic naming — are fully documented on the How It Works page.
