Jonny began his playing career at the age of 9 with the Thurlstone Brass Band near Sheffield, before moving to his first competing band, Elland Silver at the age of 12. It was at this time he auditioned to join the National Youth Brass Band of Great Britain, becoming the youngest member in the band’s history before embarking on 14 courses between 2007 and 2013. He spent 8 of these courses as the band’s principal tenor horn and won both the Katie Ogden Solo Award and Harry Mortimer Solo Award, coupled with the coveted Harold & Bernard Tovey Memorial Award when the band premiered his first major compositional work - Within the Paths of Righteousness - in 2011.
In 2009, he joined his first championship level band, joining Carlton Main Frickley Colliery on 1st horn, before moving to the same position with the Brighouse & Rastrick Band. During his time with B&R, the band won both the Yorkshire Regionals and National Championships of Great Britain. In late 2010, Jonathan made the move to Black Dyke Band, where he remained a member for 6 years, becoming the band’s principal tenor horn at the age of 18 and winning further Yorkshire Regional and National titles, plus 3 English Nationals, 2 European Championships and a British Open title during his time with the band. He also appeared on a vast number of CD recordings including the world premiere recording of a Tenor Horn concerto by Belgian composer Stan Nieuwenhuis entitled ‘This Wicked Struggle’.
In 2016, he moved to the principal horn seat at Grimethorpe Colliery Band before relocating to the North West with the Foden’s Band in 2017, winning 2 North West Regional titles and a further National Championship with the band in 2018.
As a soloist, he reached the final of the BBC Radio 2 Young Brass Award in both 2010 and 2011, before becoming only the 2nd ever tenor horn player to reach the televised category final of the BBC Young Musician of the Year in 2012. He has also appeared as a soloist with brass bands in the UK, USA, Germany, Norway and Switzerland. In 2016 he became a Performance Development Artist with Geneva Instruments, where he continued his tradition from Black Dyke Band of running an annual workshop for Tenor Horn players, attracting over 200 players across the 3 years. He has also been active in commissioning and premiering several new works for the instrument from talented young composers such as Daniel Hall, Stan Niewenhuis, Julien Roh and Dave Collins with a mixture of accompaniments ranging from brass band to electronics and tape.
