The triangular plot above shows the key structure of the music. The small ticks underneath the plot indicate barlines, with the music starting on the left side of the plot, progressing towards the right. The vertical axis of the plot indicates the amount of music used in the key analysis, from short snippets of music at the bottom of the plot which gradually increase in size higher up in the plot. For example, the top-most point in the plot represents a key analysis result when all of the music is considered. Small colored regions near the bottom of the plot typically represent chord roots. The relative strength of a key region is indicated by its height in the plot, with brief tonicizations being small, and major modulations reaching higher up in the plot. Each pixel in the plot represents an independent automatic key analysis of a range of notes within the music. To visualise the range of notes in the music which are used for each analysis, imagine a smaller triangle with the same aspect ratio of the overall plot whose apex rests on the pixel in question. The colored keyboard underneath the plot shows the key-to-color mappings being used. Each pitch in the keyboard contains a lighter and darker hue of the same color; the lighter color represents a major key with a tonic on that pitch, and the darker color represents a minor key. You can also view a functional harmonic color mapping (equivalent to transposing the music to C).
