"Conductor Karl Geiger has ensured they can turn a shapely phrase with the best and they are not short on tonal polish and sprightly rhythm either."


The Advertiser, December 2014



Graduate Singers, or ‘Grads,’ is “one of Adelaide’s finest choirs” (The Advertiser, 2016) and has been a dynamic member of the vibrant local choral scene for over 40 years. Grads has received critical acclaim as an exponent of fine choral music and enjoys a reputation for excellence throughout every aspect of presentation and performance. 


Grads is committed to presenting high quality, accessible and diverse concerts, keeping the choral tradition alive and fresh. Grads prides itself on its versatility, being equally at home with large-scale choral standards as with intimate chamber works. In particular, Grads is an exponent of 20th and 21st century music, and has given numerous premiere performances of works by local and international composers. 


With its roots in university choral societies, Grads maintains a connection to its history through involvement with the local choral community. Grads is proud that its membership represents a wide cross-section of our community, comprising experienced singers from all walks of life - from doctors to engineers, teachers, students, and professional musicians. 


Grads regularly collaborates with organisations and artists, both established and emerging. In addition to presenting its own concert series, Grads maintains a busy schedule of freelance engagements. Recent highlights include a Musica Viva masterclass with Choir of Trinity College, Cambridge conductor Stephen Layton, and performances with the Adelaide Symphony Orchestra, Band of the South Australian Police, City of Adelaide, Norwood Symphony Orchestra, Adelaide Wind Orchestra, and the Adelaide Summer Orchestra in support of the Save the Children charity.

Past directors include conductor and vocalist Timothy Marks, founder and director of Adelaide Chamber Singers Carl Crossin OAM, and conductor and ABC Classic FM presenter Graham Abbott.

Karl Geiger, Director of Music


Karl Geiger is a pianist, organist, and conductor who relishes in creating music with others. As a young musician, he was drawn to one of the first collaborative activities he was exposed to - choral music - and hasn’t looked back since.


Moving from chorister to accompanist to conductor was a natural progression for Karl. With this complimentary set of skills, he often wears several ‘hats,’ moving with ease between the podium and the keyboard. As a choral accompanist, Karl’s principal long-term roles include the First Concert Choir of Young Adelaide Voices (2010 to 2016) and the choirs of the Elder Conservatorium of Music, in particular the Elder Conservatorium Chorale (since 2011).

A versatile accompanist, Karl regularly performs as pianist, organist and harpsichordist. He was the inaugural winner of the Diana Harris Prize for Accompanying, and the winner of the 2010 Geoffrey Parsons Award for Accompaniment. Karl was Organ Scholar at St Peter’s Cathedral for two years, and has had extensive experience as a collaborative pianist and orchestral continuo player.


Karl first studied conducting under Carl Crossin OAM at the Elder Conservatorium of Music. As an emerging conductor, Karl participated in the Gondwana National Choral School conductor’s development program, and has conducted in masterclasses with the King’s Singers, Stephen Cleobury (Choir of Kings College, Cambridge), and Stephen Layton (Choir of Trinity College, Cambridge).


Karl’s principal role as a choral conductor has been as Director of Music of Graduate Singers, since 2012. In this time, Karl has enjoyed conducting the choir’s annual subscription concerts, as well as numerous other engagements, highlights of which include chorusmastering for the 2015 Doctor Who Symphonic Spectacular, and for the Adelaide Symphony Orchestra’s Harry Potter in Concert series.


In 2017, Karl was thrilled to be part of Graduate Singers 40th anniversary celebrations, which included recording and producing the choir’s first commercially available CD, Jubilate in Music.
