which musical notation software is best for guitar-playing songwriter

Which music notation software programs are the best for someone who simply wants to compose by playing a guitar and singing?

I can highly recommend Musescore for that. The learning curve isn’t too steep and it’s wicked easy to use once you get past some basic stuff. I use it every day, practically. And it’s FREE which is hard to believe considering what you get, but true. Download it here

Here are a couple of tunes I wrote using Musescore while on vacation in New Orleans. You can easily see- the program has tons of capabilities. Enjoy!
