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
B-flat major B-flat major In music theory, B-flat major is a major scale based on B, with pitches B, C, D, E, F, G, and A. Its key signature has two flats. Its relative minor is G minor and its parallel minor is B-flat minor. The B-flat major scale is: \override Score.TimeSignature #'stencil = ##f \relative c' { </score> Many transposing instruments are pitched in B-flat major, including the clarinet, trumpet, tenor saxophone, and soprano saxophone. As a result, B-flat major is a popular key for concert band compositions. In Nordic, Baltic, Western and Southern Slavic (except Bulgarian) languages, Hungarian, German and
