Select keys and click on "Find scale" to analyze the scale.

Find scales by selecting piano keys and clicking "Find scale". Start over again by clicking "Clear". Switch between sharps and flats by clicking the "# / b".

Avoid duplicates when selecting keys. For example, C Major is detected by the notes C, D, E, F, G, A, B whereas C, D, E, F, G, A, B, C will not return a scale.
