6th November 2025
Katz Praatz has announced the release of Jazz Sketch version 1.5. This update adds 144 new chord progressions to the previously available 744 in version 1.4, bringing the total to 888 jazz chord progressions.
Jazz Sketch is a simple chord sequencer designed to help you create music by arranging 888 jazz chord progressions and 168 tension chords. You can export the chord sequence (the chord progressions and chords you've arranged) as a MIDI file to play it or edit it in your DAW. With Jazz Sketch, you can create sophisticated, jazz-infused song with ease. Additionally, Jazz Sketch allows you to learn jazz harmony by playing it yourself. In fact, Jazz Sketch is a small but highly useful software tool.
Jazz Sketch is a software written in JAVA, and the file extension is .jar. By default, Jazz Sketch runs well on any computer that has JAVA or JRE (Java Runtime Environment) version 8 or later installed, regardless of the operating system—for example, Windows, MacOS, or Linux. If your computer does not have JAVA or JRE installed, or if JAVA is installed but the version is earlier than 8, please click this link to download the JAVA 8 compatible with your computer's operating system:
