Sometime in the early 90′s WK came up with a different way to practice scales and chords. Until then it had been arpeggio/scale patterns and chord forms/shapes, the usual routines. But eventually that wasn’t cutting it musically anymore. “I wanted something more comprehensive, creative…so I started over and tried something new,” Krantz says.
The change immediately felt right. He dedicated himself to it, refining the rules as he went along, ready to bag the whole thing if it ever looked like a dead end. But it never did. It continued to be an inspiring, effective way for him to practice, year after year, and for most of his students too.
He kept notes about it, thinking maybe it would be a book someday. It took ten years to actually sit down and write the thing. While in South America for a few months in ’04, with few distractions, he was able to put most of it together.
For anybody bored with their practice routine, or in a rut, or feeling that no matter how many hours you practice -7b5 arpeggios you STILL can’t play over the chord, check out “An Improviser’s OS”, HERE.
