About the Diatonic Bell


Pierre Audétat conceived and constructed empirically the first Diatonic Bell in 2006. This system provides a map of the 462 heptationic modes. Having verified mathematically the correctness of the procedure in 2008, Julien Junod applied it to the pentatonic modes. The procedure, being further generalisable to other temperaments, yields this atlas of modes.


At its inception, this project earned support from the Musical Representations team at IRCAM, and from Lausanne’s University of Music.
