SeeScore is a new type of music score display intended for musicians to practice or perform instrumental or vocal music from the iPad instead of using conventional paper scores. Unlike existing score display apps using fixed layout formats such as pdf, SeeScore uses the power of MusicXML to allow interactive flexible layout, and get the best use of the limited screen size. You supply your own scores in MusicXML format which can be found on many web sites, or can be output direct from most score-writing packages, and are transferred into SeeScore through iTunes. SeeScore Lite is a demonstrator for SeeScore which has many other features, most of which can only be tried on the sample score provided.
Note that SeeScore Lite no longer allows upgrade. You must download SeeScore from the App Store when you want to upgrade.
