Released November 2025, The Protean Chord For Jazz Guitar is in many ways a response to the many calls for Ged Brockie to write a follow up to “Upper Structures, Synonyms & Slash Voicings For Jazz Guitar”.
The book is not as long as its predecesor coming in at just over 200 pages, however, the resources that accompany the book are massive. With nearly 1.5GB of information included in over two hundred and sixty indexed files including video, mp3 and MIDI files. These resources stack up to over five hours of content.
