Digital Fake Book

I use and love Lyricist (linked above the posts section in my blog), but if you don't want to spend any money, there's a free application out there called Digital Fake Book.

It might not have the features that Lyricist has, but it's a great tool also for songwriters who want to get the chords and words down (especially from guitar). From the website:

• Keeps all your songs in one place for easy, one-click selection.
• Built-in metronome with tempo setting for each song.
• Audio file linking with A/B section looping helps with learning songs by ear.
• Text size and sheet divider position is saved with each song enabling the largest text size possible while still fitting the whole song on the screen.
• Random sets can be created to make practice more varied.
• Several color schemes (themes) to choose from.
