Tessellations 1 is an autobiography or a journey that started on an old upright piano in a garage soon after I reached double figures.
In 1975, at the age of 25, I moved with my young family to Hertfordshire after being accepted and given a grandiose title 'Fellow of the Digswell Arts Trust'. I was then able to work on developing some ideas through research.
Much later, in 1999, there was support from the Peter Whittingham Foundation to write a piece of music based on research into pentatonic scales (scales having five different notes) and how certain scales relate to each other.
Tessellations 1 is a continuous longform piece lasting one hour that uses 52 pentatonic scales. Each scale has a defined frame for improvising in the moment. Each scale also moves one note differently from the previous scale in order to create a harmonic link, which changes either seamlessly or more dramatically. It reflects most of the ideas mentioned in the research. Each scale has two pre-established areas which are then developed and explored using improvisation. Because the piece is continuous, the player and listeners take part in a journey that lasts about one hour.
As a teenager, I enjoyed listening to North Indian Classical music. Tessellations 1 is similarly divided into two parts - the first part in 'free time(s)', and the second - 'in time'. It also very roughly follows the four classic elements: the first part air and water and the second part earth and fire.
Two years after the commission, on 24th November 2001, the piece was performed live and recorded in Cheltenham in a big college church on a very nice rebuilt German concert grand piano. The gig was very kindly organised by Chris Cundy and recorded by Chris Trent. Chris placed the microphones inside the piano in order to avoid the lively acoustics of the space which means that the listener also sits in the driver's seat during the journey.
The name 'Tessellations', of which there are now six compositions/improvisations, has been used because they contain structures which have, by coincidence, similarities with some of the principles of geometric tessellations. Visual interlocking symmetries and geometric shapes are transferred to the audible world of pitches, rhythm and counterpoint, with the spirit and energy of jazz, improvisation and folk music always at the heart of the performance.

The uncertainty of the next moment and the perfect choice of expression, intensity and tension. This record is not only of historical value, it is the equivalent of seeing a phenomenon that has never been seen before. A fundamental thing. jiristepan
