Leo Geyer

composer | conductor

"Leo is fast making a name for himself as one of the great young British conductors to watch". 

James Murphy, CEO, Royal Philharmonic Society 


Leo Geyer is a young composer and conductor with a passion for imaginative, daring and dramatic approaches to music-making, encompassing new work, interdisciplinary collaborations and reimaginings of existing music. He is the Founder and Artistic Director of Constella OperaBallet and Music Director for the Devon Philharmonic Orchestra and works as a guest artist internationally. Leo is also the Senior Music Scholar at St. Catherine’s College, Oxford studying for a doctorate in opera-ballet composition under the supervision of Prof. Robert Saxton. Alongside his composing and conducting endeavours, Leo recently joined the BBC Open Music Programme on the pathway to become a presenter for Radio 3 and the BBC Proms. 

Aged 19, Leo founded an orchestra which has now grown to become Constella OperaBallet – the world’s only company dedicated to the fusion of opera and ballet. Leo has brought together internationally renowned artists in over 75 critically acclaimed performances across the UK, including radio and television broadcasts. During the pandemic, Gramophone Magazine described Constella as "one of the organisations keeping music alive” for Connecting Stars - a live and interactive virtual performance programme for care home residents across the UK. Having given 200 virtual performance over the last year, Arts Council England awarded Constella £60,000 to significantly expand the programme.

Leo has received various accolades for composition, having most recently been awarded the Lord Mayor’s Composition Prize. He has received particular acclaim for his stage works, including his opera The Mermaid of Zennor, described by The Times as “imaginative and beautifully shaped”. Leo has fulfilled major commissions, which include works for the European Capital of Culture, Tate St. Ives, Opera North, Rambert Dance Company and BBC Singers. Leo is also establishing a reputation for his "reimaginings," which creatively engage with music of the past to extend its significance for today's audiences. Most notably this has included the addition of a chorus to Elgar's Enigma Variations to provide a possible solution to the "enigma puzzle". 

Leo began his conducting career at the Royal Opera House as a Cover Conductor for The Royal Ballet. Leo now enjoys a busy and diverse portfolio in opera, ballet, theatre and concert music. As well as his current conducting positions, Leo works as a guest conductor collaborating with English National Opera, English Chamber Orchestra, National Theatre, Ensemble 212 (USA) and AUT (Denmark). He has been described by James Murphy, CEO of the Royal Philharmonic Society as “one of the great young British conductors to watch”.


London-born, Leo studied at Manchester University and the Royal Northern College of Music on the Joint Course, graduating with two first class degrees and The Soroptimists International of Manchester Award for Composers/Conductors. As part of his studies, Leo also attended the Vienna University of Music and Performing Arts to study conducting with Uroš Lajovic.

Suzy Klein, BBC Radio 3 

"Geyer’s skill at dissolving elevated speech into aria, duet and trio set up the ebb and flow of musical tides."
