B-flat minor is traditionally a 'dark' key. Important oboe solos in this key in the orchestral literature include the second movement of Tchaikovsky's Symphony No. 4, which depicts "the feeling that you get when you are all alone", in Tchaikovsky's words. Tchaikovsky's Piano Concerto No. 1 is also in B-flat minor. An Alpine Symphony by Richard Strauss begins and ends in B-flat minor.
