ImproViz: Visual Explorations of Jazz Improvisations

October 9th, 2005 | Filed under: Mapping | No Comments »

ImproViz, by Jon Snydal and Marti Hearst, diagrams the melodic landscapes (general contours of musical phrasing) and harmonic palettes (musician’s tendency to use a particular combination of notes) of jazz improvisation. Viewing the jazz standard All Blues through the lens of ImproViz illustrates the contrasting melodic and harmonic styles of three musicians. This analysis uncovers some surprises, such as how Miles Davis played musical ideas that contradicted his own composition. ImproViz offers jazz students a new way to study jazz theory and can also serve as a real-time improvisational aid, allowing a student to borrow the harmonic vocabulary of jazz masters.
