Which minor key corresponds to 1 flat?

The minor key that corresponds to 1 flat is D minor. This can be determined by understanding the key signatures of the minor keys.

D minor is the relative minor of F major, which has 1 flat in its key signature. This connection between the relative major and minor keys is essential in identifying the correct key. In music theory, every major key has a corresponding minor key that shares the same key signature. For D minor, the notes are D, E, F, G, A, B, and C, forming its natural minor scale, and all fit within the key signature that has one flat.

In contrast, the other options have different key signatures: A minor, which is the relative minor of C major (no flats), B minor, which correlates with D major (two sharps), and E minor, associated with G major (one sharp). Understanding these relationships will help reinforce the identification of key signatures and their corresponding minor keys.
