The Chester Music Society Celebrity Concerts Christmas event takes place on Wednesday, December 9 at 7.30pm at St Mary’s Centre in Chester.

It features the renowned Fibonacci Sequence Chamber Ensemble visiting the society for the first time - plus the seasonal wine and refreshments.

The main work is the popular Trout Quintet for strings and piano by Schubert.

The Fibonacci Sequence is now well established as one of the foremost chamber ensembles in Britain. Composed of musicians of international repute it tailors the artists to the repertoire and enjoys warm receptions from its audiences, whether playing at music clubs across the country or at London venues such as the Wigmore Hall.

Last year’s schedule saw the recording of chamber works by Alan Rawsthorne for ASV, which was released in July last year, as well as several broadcasts for BBC Radio 3.

Numbers count

The group is named after Leonardo of Pisa, known as Fibonacci, a great medieval mathematician. The series of numbers named after him occurs throughout the natural world in the most extraordinary way, appearing as if by magic in petals of flowers, branches of trees, spirals and many more complex ways.

The relation of the numbers to each other is directly connected to the Golden Section, held by many to determine the most harmonious proportions in art and music.

As well as the Trout Quintet, they will play Notturno by Schubert, Duetto by Rossini and Mozart’s Piano Quartet in G minor.

Tickets including wine and refreshments are £17 and available from 07831 710558, the Visitor Information Centre, Town Hall Square, Chester or via the website www.chestermusicsociety.org.uk.
