NineKeys a music sight reading and practice drill program.
NineKeys uses an adaptive question algorithm to improve weak areas in your knowledge.
Each time you use the application it learns which notes you are having problems with and concentrates questions in those areas.
To visualise where you are having problems identifying notes a graphical statistics page overlays the percentage of correct answers over a stave of notes.
This is a new release, if you encounter any problems please email us support@ninelocks.com
