Eine Kleine Nachtmusik (A Little Night Music) is a suite of movements for string orchestra by Wolfgang Amadeus Mozart. Its charm and rich melodies have long made it a favourite among audiences and from time to time it can be heard on television, in films or accompanying adverts. The opening movement featured here is full of boisterous good humour. This particular arrangement is for oboe and piano, and you can print the individual parts here: Oboe part and Piano part. Here is the original version for String Orchestra and alternative arrangements for these instruments: Flute, Cor Anglais, Clarinet in A, Clarinet in B-flat, Alto Sax, Trumpet and Violin, all with Piano accompaniment.
On the Music Room site you can find the complete Eine Kleine Nachtmusik for Solo Piano and the Full Miniature Score along with the "Serenata Notturna" and "Sinfonia Concertante".
