What problem does it solve? Writing or arranging in a jazz idiom requires knowing which devices are genuinely jazz-specific versus general music theory, and which jazz techniques can transfer into pop or other styles without sounding wrong. This Skill separates the two and gives concrete rules for chord-scale thinking, comping, and jazz form. ## Core Features & Use Cases - Transfer Table: An explicit table marking which jazz devices (II-V-I, tensions, altered dominants, comping rhythms, swing feel) can or cannot move into pop, city pop, and other genres. - Chord-Scale & Melodic Minor Harmony: Reference tables covering modes, avoid notes, melodic minor interchangeability, diminished and whole-tone resources, and blues harmony variants. - Measured Arrangement Data: Corpus measurements showing jazz arrangements use smaller rosters (about 22 tracks vs 36 for pop) and fewer entry/exit events, guiding realistic instrumentation choices. - Use Case: When a pop progression needs jazz reharmonization, consult the transfer table to add Lydian Dominant color without importing altered dominants or bebop licks that would read as pure jazz. ## Quick Start Use the mc-style-jazz skill to reharmonize this pop chord progression with jazz colors that stay appropriate for the genre.
