The key signature for B major is the least sharp key signature with three "lines" of sharps. In the treble clef, putting the sharp for A on its expected position relative to the sharp for G would require a ledger line. In the alto and bass clefs it would be possible to do this, but because in piano music (which uses the treble and bass clefs) this would result in a dissimilarity between the two staves that might throw off sight-reading, this is not usually done. However, it is occasionally found, resulting in the A-sharp in the bass-clef key signature appearing on the top line. In the tenor clef, which occurs in orchestral music, the B major key signature is usually written in just two "lines" of sharps.
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, including the Second Symphony by the Canadian composer Robert Farnon, and Glazunov's Second Piano Concerto (which ends not in B, but in E). Haydn's Symphony No. 46 is in B major.
Note that in German and most Central and Northern European languages, the pitch B is called "H" while B♭ is called "B". This includes Nordic, Baltic, Western and Southern Slavic (except Bulgarian) languages as well as Hungarian.
