Pere Soto has spent three years mapping this harmonic system fret by fret, by hand — no publisher, no grant, no institution behind it. The Monster Chord Book exists because one guitarist took on a personal challenge that, as far as he knows, no one had attempted before: a real, complete harmonic reference for the entire fretboard.
Publishing the complete, 48-volume set is the culmination of that work. A project this size only exists because the people who use it help carry it forward — every purchase supports the ongoing upkeep, correction, and refinement of this reference.
It is also an invitation into the heart of the instrument in a way rarely attempted — not the easy parts, not the popular parts, but all of it. A pursuit that may never quite feel finished, because that is exactly where knowledge turns into wisdom, and craft into a lasting passion for music.
