In music theory, a major scale and a minor scale that have the same starting note (tonic) are called parallel keys and are said to be in a parallel relationship. For example, G major and G minor have the same tonic (G) but have different modes, so G minor is the parallel minor of G major. This relationship is different from that of relative keys, a pair of major and minor scales that share the same notes but start on different tonics (e.g., G major and E minor).
A major scale can be transformed to its parallel minor by lowering the third, sixth, and seventh scale degrees, and a minor scale can be transformed to its parallel major by raising those same scale degrees.
