About this masterclass
Jazz guitarist and educator Genil Castro introduces bebop scales through the lens of his Life Vest Arpeggio concept in this 38-minute masterclass — the third lesson in his improvisation series, following Life Vest Arpeggio I and II. The focus is the "chroma zone": the chromatic world that surrounds the arpeggios you already use for preparation and resolution.
What's covered
- Bebop dominant scales derived from Major, Harmonic Major, Harmonic Minor, and Melodic Minor scales
- Review of visualization strategies for applying arpeggios over II-V-I in major and minor keys
- Staying in one position so chords, scales, and arpeggios are seen as one complete picture
- Mixing arpeggios with bebop scales for chromatic lines over common progressions and static chords
- Why chromatic notes belong on the upbeat — and how placing them on the downbeat destabilizes the harmony
- Two ways of thinking about preparation: the Pat Martino "everything is minor" approach vs. the Joe Pass "everything is dominant" approach
- Tips for studying Linear Expressions by Pat Martino
A focused next step for improvisers who have the arpeggio framework down and want to add chromaticism and tension without losing the harmony.
Full class: 38 min — includes a 6-page PDF and a 3-minute audio track.
