To substitute a Neapolitan 6 chord in first inversion across a symphonic score, you'd need to identify the chord structure and enter each note across every instrument individually. By the time you've done that, the idea that sparked it has faded.

Ideas slip away in the time it takes to write them down. Traditional notation software—Sibelius, Finale—is rigid and detail-heavy. Keyboard shortcuts and MIDI help, but they only go so far.

Key Takeaways

• MusicIDE is Cursor for music: prompt-driven editing of notation with AI that understands theory.
• Say "Neapolitan 6" and it generates a Db major chord with F in the bass. It knows keys, inversions, and orchestration.
• AI won't excel at original composition yet. But editing based on historical patterns and theoretical conventions? That's tractable now.

The Vision

Like Cursor for code, MusicIDE lets you prompt the system to handle edits—generating and applying changes across the score while you review and refine.

The tool needs to understand:

• What a Neapolitan chord is
• What "six" refers to (first inversion)
• The notes in every key
• How to apply substitutions across all instruments

Some traditionalists will call this blasphemy. But this isn't replacing composition—it's extending the indeterminacy and curated unpredictability that composers have explored for over a century.

Generated Music?

"Generated" is the right word—though what we're building differs from tools like Suno, which can already outperform many musicians and, understandably, stir up some frustration.

But the reality is: either adapt to these tools or risk falling behind.

Record labels are heading in the same direction—they're just slower, partly due to less tech fluency and partly because of legal barriers. Suno, on the other hand, doesn't seem too concerned with those.

MusicIDE is more than just a generative AI wrapper. It's a power tool for composers and musicians, designed to explore deep permutations of musical concepts, reference historical examples, and help users learn through their instrument of choice. Future AR integrations and Guitar Hero–style visuals will also offer an interactive, intuitive way to practice and internalize musical ideas.

Eventually, MusicIDE will be open source, supporting plugins that enable a wide range of use cases—from virtual reality instrument training to robotic symphonies.

Applications

The overarching goal is to support music research and composition by giving individuals access to the same analytical and creative tools that history's most outstanding musicologists, composers, and performers have used.

Development is ongoing, with public access planned for a future release. The name may change.
