Teaching ArtistBryan Parker

Bryan decided that he wanted to play a brass instrument – the Euphonium – in Grade 8 at Philemon Wright High School, shortly after his first music teacher had demonstrated all of the band instruments. Over the next few years, Bryan learned to play the trombone at the suggestion of his second music teacher in order to play in the school’s jazz band, which gradually led to the bass trombone. Bryan recognizes and greatly appreciates the early influence of both of his high school music teachers.

Bryan’s formative musical experiences were playing the bass trombone in the Heritage College Big Band and the Ottawa Youth Orchestra. The latter gave Bryan his first taste of orchestral playing – Mars, from Gustav Holst’s The Planets – and orchestral music continues to be a major source of musical fulfilment. Bryan learned much under the baton of John Gomez, and looks back on those years with fondness and gratitude.

Bryan later obtained a Bachelor of Music degree from the University of Ottawa, where he studied under Douglas Burden (bass trombonist, National Arts Centre Orchestra). He also played in the University Orchestra (David Currie) and sang in the Choral Ensemble (Lawrence Ewashko). Bryan’s approach to teaching music is strongly influenced by his experience working with these three musicians and pedagogues.

Bryan joined the Ottawa Youth Orchestra Academy (OYOA) faculty for the 2004/2005 season as director of the Junior Brass Ensemble, to which an Intermediate Brass Ensemble was added in the 2016/2017 season. Having marked his fifteenth year with the OYOA in 2019/2020, Bryan continues to feel that working with young brass students is one of his favourite musical activities.

Since the fall of 2018, it has been Bryan’s great pleasure to be a Teaching Artist with Orkidstra, where he teaches low brass and conducts the Junior Concert Band at the Centretown Hub. He looks forward to taking a few brass ensembles under his wing in the fall of 2020. Orkidstra’s mission to empower kids from under-served communities by teaching life skills (e.g. teamwork, commitment, respect and pride in achievement) through the universal language of music resonates strongly with Bryan, and he is grateful to have the opportunity to be a part of this truly inspiring organization and work with some wonderful young people. The experience continues to expand Bryan’s horizons as a music teacher.

For many years, Bryan has been an active member of the local music scene. He has been the bass trombonist of the Ottawa Chamber Orchestra since 2005, and held the same chair in the Divertimento Orchestra from 2013 to 2018. He has been a church musician, notably at St. Brigid’s and St. John the Evangelist, and has on many occasions played as a freelance trombonist in the community.

An avid chorister, Bryan has sung with the Ottawa Festival Chorus, the Ottawa Choral Society and is currently a member of the Ewashko Singers. Over the years, he has participated in many interesting concerts at the National Arts Centre and elsewhere in the community. Highlights include Bach’s B Minor Mass (Rilling), Beethoven’s Missa Solemnis (Zuckerman), Mahler’s Eighth Symphony (Nezet-Séguin), Britten’s War Requiem (Shelley), and La Machine (at LeBreton Flats with a giant mechanical spider and fire-breathing dragon!)

Teaching ArtistDaniel Friedberg

Music has been one of Daniel’s biggest passions throughout his life. In middle school, Daniel chanced upon a piano while on vacation at a relative’s house, and felt an instant connection to it! He took to the piano so eagerly that he started learning Grade 9 RCM pieces after just two years of playing, and was set on becoming a concert pianist one day. Daniel then attended the Claude Watson Program for the Arts at Earl Haig S.S., where he majored in Piano Performance, although he likes to joke that he actually majored in Vocal Performance due to his involvement with the Earl Haig Singers Choir. This spurred him to take part in the McMaster University Choir throughout his undergraduate degree, which he had the privilege of leading in his graduating year as President of the Choir. Daniel simultaneously nurtured a passion for science and medicine in his Bachelor’s degree in Health Sciences. These two passions of music and medicine led him to do research in and learn about the scientific, neurological, and therapeutic aspects and powers of music, which he believes strongly.

I was able to gain real practical experience at OrKidstra: it was a great opportunity for me to take the skills I was learning in my university pedagogy and conducting classes, and apply them in real-life situations.
