New App, Rhythm Necklace, Lets You Explore The Geometry Of Rhythm

rhythm-necklace-appRhythm Necklace is a new ‘geometric sequencer’ for iOS, designed to let you explore the geometry of rhythm.

The concept of ‘Rhythm necklaces’ – circular representations of repeating patterns – comes from author Godfried T. Toussaint’s book, The Geometry of Musical Rhythm.

According to Toussaint, circular representations of rhythms show the underlying geometric properties that make them enjoyable, such as the degrees of evenness and symmetry.

And Toussaint has found that analyzing rhythms geometrically reveals relationships between rhythms the world over. For example, a core group of geometric algorithms are shared in rhythms iused in African, Cuban, Balkan, and Spanish folk music. Continue reading

Euclidean Rhythm Generator Rack Extension For Reason

Robotic Bean Creative has introduced Euclid Rhythm Generator, a Euclidean rhythm generator Rack Extension for Propeller Reason.

Here’s what they have to say about it:

Euclid is rhythmical inspiration in a box. You can use it to spice up your existing songs, or to start building up new ones from scratch. It’s a constant source of surprises and happy accidents for your productions. And there are plenty of presets included to help you get started or provide you with inspiration to build your own.

Euclid may seem simple on the surface, but it gets really deep once you start unlocking its secrets. You can automate and modulate basically every parameter, and each of the four gate outputs gives you a unique variation of the same pattern.

It comes with a big graphical display that visualizes your pattern in real time, including gate width, velocity, shuffle amount and current play position. The display also shows you all actual parameter values, taking CV modulation into account.

Euclidean Sequencer For Modular Synthesizers


Club Of The Knobs has introduced the C969 Euclidean Bi-Clock Sequencer, a new modular for Moog style modular synthesizers.

The Euclidean sequencer is a 4-channel gate sequencer, ‘specially suited for he creation of poly-rhythms’. Each sequence can be from 2 to 32 steps in length.

In addition to delivering the gate sequence to two outputs, the ‘silent steps’ in the sequence are available via a ‘Silence Gate Out’.

The idea of ‘Euclidean Rhythms’ was discussed by computer scientist Godfried Toussaint in his paper The Euclidean Algorithm Generates Traditional Musical Rhythms (pdf). He argues that the Euclidean algorithm may be used to generate ‘a large family of rhythms used as timelines (ostinatos), in sub-Saharan African music in particular, and world music in general. These rhythms have the property that their onset patterns are distributed as evenly as possible.’
