I actually use “Personal Composer”. I input both from a keyboard and through the mouse. It actually takes less time to do it through the mouse, since the program which does the keyboard-score transfer is unreliable, and you spend more time correcting the input than when using the mouse (a bit like these type-voice programs).
I heard wonders about Sibelius, but the price is pretty scary, and I have been told by several people that “Music Publisher” is as good or better at a 10th of the price. You can get more details at
www.muspub.comBesides being useful for students, rewriting a score has several beneficial side effects: it teaches you a lot about theory, harmony, the architecture of the piece, it improves sight reading, analysis, you name it.
In fact these days when I want to learn a piece myself, I never do it from the original score. My first step is always to rewrite it. By the time I go to the piano I already “know” the piece just from writing it (of course as I rewrite it I am very aware of everything – I am not just copying in a mechanical way).
Best wishes,
Bernhard.
