What is bartok 2nd piano concerto?

Béla Bartók's Second Piano Concerto is a significant piece of modern classical music from the 20th century. The work was commissioned by Serge Koussevitzky who was a conductor of the Boston Symphony Orchestra.

Bartók wrote the concerto during the period of his life when he was experiencing financial difficulties and an increasing lack of recognition for his work. However, the Second Piano Concerto, which was premiered in 1933, was incredibly successful and helped restore Bartók's reputation.

The concerto is in three movements - the first being a slow and contemplative sonata form with a free rhapsodic introduction; the second is a scherzo, again in a free form with a lively and percussive character, and the finale is highly energetic, with an aggressive and rapid rhythm.

The structure of the concerto is very tight and concise, with each movement highlighting Bartók's unique style of music. In particular, his use of folk melodies, harmonies, and rhythms, as well as his innovative approach to pianistic effects and virtuosity is prominent throughout the work.

Overall, the Second Piano Concerto is considered to be one of Bartók's most important works, and it remains a favourite of many pianists and audiences around the world.
