<P> In music, a major scale and a minor scale that have the same tonic are called parallel keys and are said to be in a parallel relationship . The parallel minor or tonic minor of a particular major key is the minor key based on the same tonic; similarly the parallel major has the same tonic as the minor key (from the Greek, para alleilos, "beside each other"). For example, G major and G minor have different modes but both have the same tonic, G; so we say that G minor is the parallel minor of G major . In contrast, a major scale and a minor scale that have the same key signature (and therefore different tonics) are called relative keys . </P> <P> A major scale can be transformed to its parallel minor by flattening the third, sixth, and seventh scale degrees, and a minor scale can be transformed to its parallel major by sharpening those same scale degrees . </P>

What type of keys have the same tonic but different key signatures
