My family and I are living near Hamburg, Germany. I am an engineer and a an amateur musician. Years ago I started some private research to find out, why the octave has historically been divided into twelve chunks of more or less the same size – so I entered the field of partials, temperament and dynamic intonation.

I came across Bill Sethares’ awesome book Tuning, Timbre, Spectrum, Scale (TTSS). With regard to my own experiments, certain basic aspects discussed there seemed familiar and I was happy to find that I was not completely on the wrong track. Today my copy of TTSS has been a true companion for almost two decades.

Working with chords built from Overtone Scales has always been one of my favorite playing fields. I utilize Tim Thompson’s KeyKit – a light weight and MIDI-centric programming language – for practical exploration. KeyKit realtime code controls the intonation of two prototypical electronic instruments I built: A keyboard-driven setup and a playing console that extends the concept of a pedalsteel guitar.

My first contribution to this Wiki was an article about just intervals generated by an ancient Hammond Organ - you might read it with a wink...

The title of the second Xenwiki page I created is Expanding tonal space, an article that describes useful visual arrangements of a set of overtone scales.

If I have used inappropriate terminology somewhere (e.g. mode, tonic, fundamental) or you just like the concept of tonal space please leave a comment.
