We have been fans of the iPhone as a platform for guitar based applications since shortly after Apple launched its App Store.  Our favorite guitar-based application for the device is chord lookup because let’s be honest, sometimes it isn’t easy to remember the fingering for a D# maj9 on the fly.  While we often use the 7 Chords application, we must admit that Chordbook is even more robust.  Today, the developer of Chordbook released version 1.2 of the application.  The new version has many improvements including:

* a new menu for quicker navigation

* quick lookup of 2,448 guitar chords

* “what’s this chord?” reverse chord lookup

* a new more comprehensive help menu

* guitar, bass and keyboard views

If you have an iphone and don’t have 2,448 guitar chords loaded into it, this one is worth a shot.
