The diatonic bell is a graphical representation of musical modes and scales. This systematic catalogue highlights the following relationships among modes:
- The 66 scales are ordered according to their distance from the diatonic scale, the most familiar modes being concentrated around the former.
- The 462 heptatonic modes are grouped into 31 classes, ordered from the “brightest” to the “darkest”. Browse through more than 5000 audio examples in MIDI file format.
- Pierre Audétat developed this construction in 2006 in order to investigate the heptatonic modes of the equal temperament. It has since then been generalised to a wider set of temperaments. Microtonal and macrotonal bells are avaialble as well.
