The format used in this book was developed by Norm Jones, a self-taught, non-music reading ukulele enthusiast. Norm was unable to find the songs that he wanted in just a lyric/chord format so he developed his own. He later added thematic graphics to make the sheets more attractive. The music is not provided, so it is necessary that the player know the tune. However, this is a great format for people who either play, or would like to play, the ukulele but don't read music. The novelty of this format will entertain and provide enjoyment to those who are more accomplished strummers as well.
