Sibelius

Sibelius Software is a London-based software business and a part of Avid Technology that develops and sells music notation and music education software.The company was named after the Finnish composer Jean Sibelius, and was founded in April 1993 by twins Ben and Jonathan Finn to sell the Sibelius notation program. In August 2006 the company was acquired by Avid, to become part of its Digidesign division, which also manufactures the leading digital audio workstation Pro Tools.

The company has also released various other music programs, including special versions of Sibelius (e.g. for students and online publishers), add-ons for Sibelius such as extra sound libraries, and a range of software for teaching music called Sibelius Educational Suite. Some of this software was developed by other companies, and then distributed or acquired by Sibelius Software. The company also provides a sheet music self-publishing web site for composers & arrangers, SibeliusMusic.com.
