Negative Harmony Note and Chord Translator Online
What is Negative Harmony Note and Chord Translator Online?
This agent converts musical note names and chord symbols into their negative-harmony equivalents. You type space-separated tokens, and it returns the mapped tokens in the same order. A leading hyphen tells the agent to read a token as a single note rather than a chord, so -C becomes -G while a bare C becomes Cm. It is built for musicians, theory students and songwriters who want a quick, readable conversion plus a short explanation of each mapping.
Key Features
- Complete note mapping. All seventeen note spellings in the source table are supported, including flats and sharps, with enharmonic alternatives shown where the source shows them.
- Chord mapping with slash alternatives. Chord symbols such as
C7,Cm7b5,F#dim7andBaugmap to their negative-harmony counterparts, and where the source lists two equivalents they are both shown. - Hyphen disambiguation. A hyphen prefix forces note interpretation, matching the source convention exactly.
- Per-token explanation. After the converted block, the agent lists what each token became and why, so you can check the result.
- Transparent handling of unsupported tokens. Flat-written chords and unknown symbols are reported rather than silently dropped.
How to Use
- Type your notes or chords separated by single spaces. Prefix a note with a hyphen when you want note-level conversion, for example
-C -E -G. - Send the message. The agent returns a copyable block with the converted tokens in the original order.
- Read the short explanation beneath the block, then ask for a different spelling, a reversed conversion, or a clarification of any token.
Example Use Cases
- Converting a melody line to negative harmony notes. Enter
-C -D -E -F -Gand receive the mapped note sequence with enharmonic alternatives. - Checking a chord progression in negative harmony. Enter
C Am7 F#dim G7to see each chord's counterpart, including slash alternatives such asC6 / Am7. - Understanding a single ambiguous symbol. Enter
Cand-Ctogether to see the chord-versus-note distinction explained side by side.
Tips for Best Results
- Use single spaces between tokens; extra spaces are normalized but the order is preserved.
- If a chord does not convert, try its sharp spelling, since the source chord table is sharp-based.
- Ask for the reverse direction explicitly if you want to go from negative tokens back to source tokens.
FAQ
What input format does it accept?
Space-separated note names or chord symbols. Notes may use sharps or flats. A hyphen before a token forces note interpretation.
How accurate is the conversion?
The note and chord mappings are fixed tables reproduced exactly, so results are deterministic. Chords outside the table, and flat-written chords, are reported as unsupported rather than guessed.
How does this compare with some free text tools?
Some free text tools offer a similar substitution box with partial chord coverage and no explanation. This agent covers the same note set, reproduces the chord table, and adds per-token explanations and explicit unsupported-token reporting. It does not produce audio, MIDI or notation files.
