Claude Debussy's Deux Arabesques are a pair of early piano pieces which have all the hallmarks of the composer's style. They are playful and "impressionistic", and make significant use of pentatonic scales (the 5 most harmonious notes of a major scale). This first arabesque in E major is characterised by lots of flowing triplets, sometimes played in the right hand while the left plays normal quavers. The piece is full of small patterns which repeat at different pitches, which is very evident if you are able to view the midi notes in "piano roll" format. In the Alfred Hitchcock film "The Birds", the actress Tippi Hedren is seen to play some of this piece.
