I am looking for computer notation software

Hello,
I have been composing a music piece in mixed Classical and Balkans genre. I use music paper and a pencil for notation. I would like to transfer my composition to the computer. That's why I am looking for computer notation software. It should be some kind of advanced notation software. It should be capable to notate the following:
- Change time and key signature in the middle of composition
- tuplets 5 sixteenth notes = 2 eighth notes
- grace-notes and group of grace-notes (like that in the beginnig of 'Rhapsody in Blue')
- grouppetto (a group of grace-notes; a turn)
- text labels (like 'piu mosso', 'Tempo 1', 'tempo rubato', etc)
- the ordinary things like flats, sharps and double-sharps and etc.

Could someone of you tell me if there is such program for PC?
Best regards,
George V

Try Sibelius - this is a favourite amongst a lot of pro composers - other programs like Coda Finale are more appropriate for actual typesetting.

Thank you, Insider. I looked at the Sibeluis' website. It seems that this is the program I'm looking for.

Sibelius comes linked to a music scanning application. Depending how neat your writing has been, you may be able to scan some of your past work in, but you will need the professional version.

I have successfully scanned in handwritten scores a number of times, you miss a few things, but it's easier than starting from scratch.

PraiseTheLord,
I noticed this interesting tool. Unfortunately, my handwriting is bad. Moreover, I use the eraser very much (that is, I don't have the genius of Mozart who used to write his music without crossing out of notes) and my sheet music is unreadable to some extent.
Regards,
George

Yep! Sibelius is the way to go!
