Learn through a specific comparison
ChordLilt brings chords, scales, keys and guitar positions into a shared reference. Choose a musical question, inspect the actual notes, then hear the example when you are ready. A diagram, a note list and a short explanation describe the same selection.
The tools are useful when you want to check one detail: the third in a minor chord, the bass of an inversion, the spelling of a leading tone or the strings that carry a scale’s tonic. You do not need to identify an entire song before asking a useful question.
Keep the reasoning visible
The music results come from explicit interval patterns and spelling rules. ChordLilt shows roots separately from bass notes and keeps octave labels when register matters. Ambiguous pitch sets can have more than one compatible chord name.
Reference pages use a consistent set of root spellings so equivalent names do not create duplicate lessons. The interactive tools can explore a wider set of supported choices. The Sources page identifies the textbooks and technical references used for factual checks.
Turn an example into practice
Save examples in a named collection, arrange a short progression and return to it later. SVG diagrams and PDF sheets give you a visible reference away from the page. JSON preserves an editable collection you can import again.
Collections stay in the current browser unless you export and transfer them. There are no accounts or automatic cloud backups. The saving guide explains how to keep an independent copy.
A reference with a defined scope
Playback uses synthesized equal-tempered pitches at A4 = 440 Hz. The fretboard uses standard six-string tuning. The tools do not listen to an instrument, identify recordings or judge a performance. A correct set of notes also does not prescribe a single fingering, mood or musical interpretation.
The articles use original short examples rather than commercial song excerpts. When you encounter an unclear result, compare the note list, degree labels and stated convention, then follow the relevant guide.
