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).
There are a few large-scale works in B major. Joseph Haydn's Symphony No. 46 is in B major. See also: List of symphonies in B major. The aria "La donna è mobile" from Verdi's opera Rigoletto is in B major, as is the Flower Duet from Lakmé. Johannes Brahms's Piano Trio No. 1, Op. 8 is in B major, though the piece ends in B minor. He also wrote the slow movement to his Second Symphony in B major, as well as the fourth and last piece of the Ballades, Op. 10.
