Description by Jeffrey Emanuel (from the App Store)

Write a jazz progression, hear it immediately, and study what makes the changes connect.

FrankenJazz is a private lead-sheet and harmony workshop for iPhone, iPad, and Mac. Enter chord symbols in a compact chart, choose a key and tempo, then play the form with a responsive chord-tone piano. The app reads Roman-numeral context, traces guide-tone movement, and lets you compare five practical voicing families.

Use the bundled progression library as a starting point or build your own. Change the key, tempo, groove, instrument, and voicing while the chart remains editable. Playback includes seeking and looping for close listening and practice.

When the chart is ready, export a FrankenJazz document, plain text, or a standard MIDI file. Local recovery protects the current session if the app closes unexpectedly.

FrankenJazz works without an account or network connection. It includes no telemetry, advertising, sample downloads, or cloud processing.
