In music theory, B major is a major scale based on B. The pitches B, C♯, D♯, E, F♯, G♯, and A♯ are all part of the B major scale. Its key signature has five sharps.
B major's relative minor is G♯ minor, its parallel minor is B minor, and its enharmonic equivalent is C♭ major.
Although B major is usually thought of as a remote key (due to its distance from C major in the circle of fifths and its fairly large number of sharps), Frédéric Chopin regarded its scale as the easiest of all to play, as its black notes fit the natural positions of the fingers well; as a consequence he often assigned it first to beginning piano students, leaving the scale of C major till last because he considered it the hardest of all scales to play completely evenly (because of its complete lack of black notes).
