ChordBook v3.4 provides chord lookup and diagraming for guitar in standard or alternate tuning. ChordBook's purpose is simple--it provides a way for you to create your own, customized chord listings....in the order and with the voicing YOU choose. Chordbook is designed to work along side a graphical editor of your choosing (Excel, OpenOffice, Paint, etc.). This enables you to not only create documents of chord diagrams but also to write in lesson notes, song lyrics, and combine them with other graphics (depending on the capabilities of your editor). Over the years, this has been our user's most asked-for feature. The Neck Window -- or the Fretboard is where the real power of ChordBook lies. This window allows the browsing of chord fingerings over the neck and has a Name-that-Chord function which recognizes more than 60 different chord types in any key, in standard and non-standard tunings. These user-created chord voicings may then be diagramed in the Diagram Window.
