NoteAbility Pro is a professional music notation package
for the Macintosh OS-X operating system.
Developed by Dr. Keith Hamel at the University of British Columbia,
it is probably the most flexible music notation software available on any platform.
NoteAbility combines both musical intelligence and notational flexibility in a direct
and intuitive graphical user interface. Notate anything from simple melodies to complex
avant garde orchestral music, play the score on your MIDI synthesizer or using Quicktime
Musical Instruments and print a publishable copy of your score on any compatible printer.
If you have been frustrated by the awkwardness and inflexibility of other
notation programs, or by the time it takes to learn them, then you definitely should have a
look at NoteAbility Pro.
