B flat major
Key with two flats
B flat major is a musical key based on the B flat note, with a scale that includes two flats (B flat and E flat).
It's one of the most common keys for wind instruments, particularly brass and woodwinds, since their natural tuning often centers on B flat.
Many orchestral and band pieces are written in this key: The symphony opens in B flat major.
