Description

Concentric Rhythm is an interactive tool for generating, developing, and exploring musical patterns. It uses geometric transformations and many other simple processes to create, develop, and evolve music.
The looping musical timeline is visualized as a circle, which allows you to treat musical patterns as concentric shapes. This makes performing geometric transformations such as rotations, reflections and folding very natural and intuitive.
It also provides tools for melodic lines such as random-walk generation and scale-based inversion and transposition.
You can generate rhythmic lines using cross-rhythms or the Euclidean algorithm, and allows for great visualisations of complex polyrhythms.
Concentric Rhythm now allows you to assign each pattern to a different MIDI channel and send your results to other MIDI compatible apps or devices.
Concentric Rhythm was originally developed as a new way to improvise electronic music, but it is also a great tool experimenting with and developing musical material, or just for casually playing with music in a unique, hands-on, way.
Many of the ideas here were inspired by the book ‘The Geometry of Musical Rhythm’ and this app is a powerful tool for anyone who is interested in exploring these ideas. But at the same time is easy enough to use that anyone (even with no musical or mathematical background) can make interesting musical patterns and think about the musical world a little differently.
Note: There are known compatibility issues when used with AUM, especially on iOS 14

Concentric Rhythm Reviews

Very low subdivision , 36 seriously 🥲

It would be the best sound app ever if it has a maximum of 96 beats but i dont know the developper choosed to put a limit of 36 please upgrade it to 96 or even 64 please !

Love this tool

Helps to really see what’s happening rhythmically. Wish it could create a notable transcription for performance. Wish it was on my Mac. Thanks George

Amazing

It’s amazing. Full stop. Intuitive layout, great design and aesthetic, extremely functional. I can’t say enough good things.

This app is truly a life saver. I’m a pianist specializing in contemporary music, and I was searching for an app that I could program some of the polyrhythms that I’ve been encountering in my repertoire. I love that I can program something like 11:13, but I’m even more blown away that I can adjust it to account for dotted rhythms and rests. Ive been sharing this with practically all of my friends and colleagues in the field. Thank you Jeff for creating this!

About perfect.

I tried, but so far can’t find anything negative about this app. About as good as it gets as is! It is probably mathematically possible with all the transformations, but surprisingly I did not find an easy way of converting say a 6 note rhythm into 5 or 7 note one while keeping even distribution of notes around the circle. An “unwrap” feature could be handy, basically allowing user to convert the sequence into a more traditional rows/columns sequencer patterns (can be done by exporting MIDI into any piano roll type DAW but in app functionality would be useful). I also wish that turning the rings in relation to the other ones was not quantized and allowed in-between positions, this could create even more interesting rhythms. And if it was possible to divide any distance between two notes into subdivisions and create notes there... Once again, this app is about perfect and all above is just a fantasy... Edit: Not sure if this is a feature meant to prevent recording of IAA into an AB3 in the free version, but as soon as the AB3 is opened the app changes the sound into an echoey one and even after quitting AB3 the sound remains changed (comes back to normal if you quit the app and reload the project). IAA can be recorded in AUM without trouble which tells me the changing sound is a bug .

Amazing, amazing app. Percussion, melody, polyrhythms, midi-out—any kind of permutation you can imagine—all mixed together in glorious unison.

Polyrhythm lovers need this!

Easily create polyrhythms and morph them with different modes. A lot of fun.

Fantastic app

This is so much fun to play with! Thank you so much for developing this.

Paying for midi outputs?

michaeljjay on

Well Jeff, that post was 6 months ago? I wish I could show everyone the screenshot that I have with me. It says “Enable MIDI? Sending midi to other application/Devices is available as an in-app purchase ($4.99). If you would like to enable sending midi, select ‘Purchase Send MIDI’’. If you have reinstalled Concentric Rhythm and need to restore the purchase, select Restore Send MIDI’. It showed 6 months ago on 1 option. 1: Purchase Send Midi. After checking back 6 months later, it now shows 2 options. 1: Purchase send Midi. 2: Restore Send Midi. There was no restore send midi option when that post was made but if you were concerned about what people were saying, maybe you should pay close attention to your customers and ratings. I’ve updated my rating to 4. I had a conversation with this guy about making this app with 16 midi outputs a few months ago, even sent him some concepts. That’s when I paid for this app and midi outputs was part of the purchase. Now it still doesn’t even have 16 midi outputs and he’s charging people to use 1 midi output? Unbelievable.

My new go-to Euclid app

This is a very high quality Euclidean sequencer. Enough said.
