The text answer, formula and labelled visual are equivalent views of the selected state. Enharmonic intervals can sound alike in equal temperament without being notationally or functionally identical.
Connected theory
Follow the selected root or tonic into its hub, then into the relevant key, interval or inversion reference. Contextual links use the active subject rather than the same generic list on every page.
Try a controlled comparison
Change one selector at a time and describe what changed in the notes, degrees, bass or signature. Generated audio is optional and user initiated.
- Keep the root fixed and change quality.
- Keep the structure fixed and transpose.
- Compare the visible text with the keyboard.
