David Heyes writes: "October Morn was inspired by the beautifully atmsopheric Dorset countryside as I was driving towards Milborne Port in early October 2015. The mist was still hovering over the fields, as the cows were slowly waking and beginning to eat, and as the sun was slowly starting to break through the clouds. The opening oboe notes 'appeared' as I drowv and the piece slowly emerged as my journey continued with its modal and slow-moving music gradually taking shape."

October Morn was composed for OboeBass! (Carrie Vecchione & Rolf Erdahl) in America and is dedicated to this unique duo. It also exists in versions for flute or clarinet and double bass.

October Morn was premiered in June 2016 in Southampton by Luke Roberts (oboe) and Thea Sayer and the version for flute and double bass was premiered by Michelle Underwood (flute) and David Heyes (double bass) at The Old Java Coffee House in Teignmouth, Devon on Saturday 5 March 2016 as part of the Teignmouth Classical Music Festival. A version for tenor recorder and double bass was premiered on Saturday 14 June 2019 at St Michael the Archangel Church, Teignmouth (Devon) by Andrew Collis (tenor recorder) and David Heyes (double bass).

The US premiere of October Morn was at Southeastern Louisiana University, Hammond, Louisiana, USA on 13 February 2020 by Juaquin Corwin (oboe), Daniel Chiva Sanz (double bass).

David Heyes studied double bass with Laurence Gray and Bronwen Naish and later at the Royal College of Music in London. He completed his post-graduate studies in Prague with Frantisek Posta (Principal Double Bass, Czech Philharmonic Orchestra). He has given recitals and masterclasses in 13 countries over the past few years and has been a juror at a number of international competitions, twice as chairman.

David has been Specialist Double Bass Tutor at Wells Cathedral School for 19 years and received a prestigious award from the David Walter Charitable Trust of New York for his pioneering activities as a soloist, teacher, publisher and commissioner of new music for double bass. He works with composers throughout the world and is particularly interested to expand the double bass repertoire, by commissioning new works and by rediscovering forgotten ones. Over the past 30 years he has commissioned more than 500 works, from beginner to virtuoso, and from one to twenty basses.

David has transcribed more than 200 works for double bass, many published by Recital Music, and in recent year has also composed a number of original works for double bass which have been performed in Britain, America, Venezuela, Turkey, Spain, Mexico, Germany and Czech Republic. David is self-taught as a composer and his music has been described as lyrical, evocative and accessible, but certainly of the 21st-century.
