As chamber ensembles go, horn, oboe and piano is not exactly the commonest trio, nor would such a trio find themselves overfurnished in the repertoire department. So if anyone is to take on the task, it is the Fibonacci Sequence, one of the best ensembles in the business.

Next Friday's trio performance at Putney's St Mary's church will feature Fibonacci founder Kathron (CORR) on piano, Stephen Stirling playing horn and oboeist Christopher O'Neal, who explains why Fibonacci is up to the job: "It is one of our strengths to play off-the-wall music. We have got the whole range of intsuments so we are not limited to just a wind or string quartet.

"A more standard ensemble would find it difficult to programme for this trio."

The most notable inclusion on the programme is one of only two mainstream pieces for oboe, horn and piano - Carl Reinecke's trio in A minor, a piece which O'Neal has recorded for the BBC.

"It is a very unusual combination of instruments," continues Christopher, "and it lends itself to romantic, heroic sound. There is plenty of room for humour in the piece and it brings out the humour in the oboe and horn, which are both quite perky instruments."

Also on the programme are Schumann's Adagio and Allegro for horn and piano, Poulenc's Sonata for oboe and piano, and Schubert's Two Scherzi for solo piano.

In further Fibonacci news, the ensemble is looking to nurture some outstanding young musical talent in future concerts. It is working with top music colleges - starting with the Royal College of Music, where Kathron teaches - to invite a student to play as one of two instruments in a performance.

For example, for a trio of two oboes and a piano, one of the two oboes would be a particularly gifted student from RCM or, further down the line, perhaps Guild Hall School of Music or Trinity College, where Christopher is a professor.
