The one and only polyrhythmic play-along

In the Jam Session mode, the app decides on its own what to play and when to play it, based on the style of the song and the tempo.
Experiment with how the app transforms the rhythm and the harmony according to the slider levels.

Practice that Feels like Performance

Master your polyrhythms

Focus on a specific grouping, polyrhythm or rhythmic displacement. Ask the trio – or an individual instrument – to include only what you’ve requested when they introduce polyrhythmic phrasing.

As you won’t know when or how it will be used though, this feature also helps sharpen your ability to improvise as well as mastering that rhythm!


Genius Jazz Trio Sound

It’s all in the dynamics, note durations, space and feel.
The Genius Jamtracks trio pays close attention to each of these elements to make the Genius Jam Session experience as close to the real thing as possible.


The Only Polyrhythmic Play-along!

From the traditional comping of a standard play-along and common polyrhythms of the jazz vocabulary to more complex, challenging and sometimes superhuman rhythms, experiment with how the app transforms the rhythm according to the Rhythmic Complexity slider level.


A Real Swing Feel

Forget the robotic triplets of other play-alongs.
When changing the tempo, the app doesn’t simply play faster or slower, the swing feel changes as well. The app learned how to swing by internalizing the jazz vocabulary and playing based on real transcriptions from the masters.


The Reharmonization Department

From triads and jazz harmony to more complex chords and negative harmony.
Experiment with how the app reharmonizes each song according to the slider level.


Actual Voice Leading!

No matter what your settings are, just press play and you’ll always have the same attention to voice leading from the pianist and the same effort in creating beautiful lines from the bassist to accompany you.

Paul Bollenback


“Genius Jamtracks is easily the best play along app out there! Particularly the piano voicings are more logical and realistic than other play-along apps. The bass and drums are not just a simple repetitive pattern, but actually use some jazz language. And it’s nice that you can make the band busy in unpredictable ways. As much like playing with a real group as you can get from an algorithm. Highly recommended!“

“It’s like a jazz musician wrote it. The drums and piano are just like how a jazz drummer and pianist would play. Couldn’t be an easy task to create that!”
