Minor scale based on the accidentals of the "natural" minor scale, not on those of the harmonic or melodic minor scales. For example, a piece in E minor will have one sharp in its key signature because the E natural minor scale has one sharp (F). Major and minor keys that share the same key signature are "relative" to each other. For instance, F major is the relative major of D minor since both have key signatures with one flat. Since the natural minor scale is built on the 6th degree of the major scale, the tonic of the relative minor is
C-flat major can be seen, for example, in the Albéniz example given above: Iberia, 1st movement: "Evocación", about two-thirds of which is in 7 flats, and every bass-clef staff of which shows this variant. This is also seen in the second movement of the Beautiful Danube waltz in the Boosey & Hawkes concert band edition. C-flat major C major (or the key of C) is a major scale based on C, consisting of the pitches C, D, E, F, G, A, and B. Its key signature has seven flats. The direct enharmonic equivalent of C major is B major, a key signature
