To substitute a Neapolitan 6 chord 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.

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

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 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.

Not Suno

Tools like Suno generate music end-to-end. MusicIDE is different—a power tool for composers, not a replacement.

The distinction: Suno outputs finished tracks. MusicIDE helps you explore permutations of musical concepts, reference historical examples, and learn through your instrument. One generates for you. The other augments what you already do.

Future directions include AR integrations and Guitar Hero-style visuals for practicing and internalizing musical ideas. Eventually open source, supporting plugins from VR instrument training to robotic symphonies.

Status

Development ongoing. Public access planned for a future release. The name may change.
