Key & Scale Explorer
调性音阶探索器 · 看见并听见你的音阶
See exactly which notes live inside a key and scale, hear them played, and check whether your melody notes fit. Ten minutes with this tool will teach you more than a year of theory apps.
Check: which scales fit your melody?
Type the notes of your melody (e.g. C E G A) and see which of our scales contain all of them.
