Jazz musician Hristo Vitchev has a new book titled Pentatonic Voicings. In this book, Vitchev presents some of the ideas and concepts he’s been using to extract harmonic information from the pentatonic scale. Being one of the most universal scales and used often by most guitar players, its chordal applications come in handy to add color and enhance the sounds and hues of existing harmonic vocabulary.
On Pentatonic Voicings, Vitchev has extracted some of his favorite voicings from the “A minor” pentatonic scale. The usage and application of these voicings can happen in many different ways. Amin7, Dmin9, Cmaj7, Fmaj7, Bbmaj7 (#11), and F#7alt are among Vitchev’s favorite candidates.
The study and explorations of the concepts should start in one key (harmony) and then progressively move through all keys and standard harmonic progressions to develop a full and comfortable application for any musical situation.
