From the website:

MakeMusic®, Inc., is a world leader in music technology. Our products include Finale®, the world’s best-selling music notation software, and SmartMusic®, interactive software featuring the world’s largest accompaniment library.
For more than 20 years, Finale has been the industry standard in music notation software, enabling composers, arrangers, musicians, teachers, students, and publishers to create, edit, print, and publish musical scores.
SmartMusic is interactive software that transforms the way students practice. SmartMusic provides students and teachers with access to thousands of band, orchestra, and vocal pieces, allowing students to practice with background accompaniment and get immediate feedback on their performance. With SmartMusic, teachers can individualize instruction and document the progress of every student.
Our Market
MakeMusic’s market includes music educators and music makers worldwide. In the U.S. alone there are more than 100,000 music educators and more than 60 million active music makers.
Our Strategy
MakeMusic is the only company that creates, owns, and licenses the most advanced and patented technologies and solutions to support the composition, arranging, teaching, learning, and playing of music. This creates a major barrier to entry for competitors. Independently, MakeMusic's products are already established as market leaders. Collectively they create a huge advantage for music educators, music makers, music publishers, and other professionals serving these markets by:
Providing integrated technology, content, and web services to enhance and expand how music is taught, learned, and prepared for performance.
Providing music education content developers with a technology-enriched publishing platform that leverages their copyrighted assets while simultaneously increasing the content and value of the SmartMusic library.
Offering software solutions for engraving and electronically distributing sheet music.
