Korean violinist Hae Jeong Heidi Han first picked up a violin at the age of five. Born and raised in Korea, she continued her studies with JaeKwang Song while attending Yewon School of Arts. When Han was 13, her family moved to Vancouver, BC, Canada, and she continued her studies with Robert Davidovici. While in Canada, she served as Concertmaster of the Vancouver Youth Symphony Orchestra and won first prize at the Kiwanis Competition, the Burnaby Clef Concerto Competition, and the Young Artists of British Columbia Competition.

Han received both her bachelor’s degree and graduate performance diploma from the Peabody Conservatory of Johns Hopkins University, earning the Peabody Merit Scholarship for both programs. During her time at Peabody, Han studied with Victor Danchenko and was the Concertmaster of the Peabody Concert Orchestra. While pursuing her degrees, she won the first prize in the Marbury Competition and was awarded the Josef Kaspar Award. She was also invited to join the Keshet Eilon International Violin Mastercourse in Israel to study with Shlomo Mintz.

Currently, Han plays with the Detroit Symphony Orchestra as a second violinist and lives in Detroit, Michigan where she enjoys making great music with her colleagues and husband, DSO violinist Will Haapaniemi.

Romanian-born violinist Marian Tănău first picked up the violin at the age of 4 and began his musical education in his hometown of Timisoara, Romania. He graduated from Liceul de Muzica "Ion Vidu" where he studied violin with Maria Cleşiu. He then left for the Romanian city of Cluj-Napoca and the Conservatorul de Muzica "G. Dima," where he earned an Artists Diploma. In the United States, he earned a graduate degree from Bowling Green State University. Tănău joined the Detroit Symphony Orchestra in 1995.

Tănău has appeared as a soloist with Romanian orchestras as well as with the Chautauqua Symphony and the Bowling Green Philarmonia in the United States. He is an active chamber musician. Some of his recent projects are the recording of Paul Paray's violin sonata and string quartet for Grotto Productions Co. Critics in the prestigious Strad, Gramophone, and Fanfare magazines praised his recording of the violin sonata. Tănău is the organizer of the American Romanian Music Festival that took place with great success in Romania and the United States in March and April of 2005.

Will Haapaniemi is a violinist born in Los Angeles with Finnish ancestry. He joined the Detroit Symphony Orchestra in 2014 alongside his wife and violinist Heidi Han. Haapaniemi wanted to be a violinist from the time he was two years old, when he saw Itzhak Perlman perform on Sesame Street. Many other interests competed with his practice time—some of his favorites being the martial art Capoeira, dance, and training for his glider pilot license.

Much is owed to Haapaniemi’s master violin teachers, Yoko Takebe and Michael Gilbert of the New York Philharmonic, who he studied with at the Manhattan School of Music. In high school, Haapaniemi was fortunate to study with Mark Kaplan and fondly remembers lessons with Ruggiero Ricci in his home in Palm Springs. Also of great influence was his cousin Paul Roby of the Philadelphia Orchestra and his aunt Linda Grace, whose tireless support encouraged him to be the musician he is today. Without the phenomenal support of Haapaniemi’s parents, none of this would have been possible.

Haapaniemi is active as a soloist and chamber musician, occasionally throwing viola into the mix. An avid outdoorsman, he hikes at every opportunity, and pays homage to his Finnish heritage by skiing during the winter.

Jeremy Crosmer is a remarkable artist—both as a cellist and a composer. He completed multiple graduate degrees from the University of Michigan in cello, composition, and theory pedagogy, and received his DMA in 2012 at age 24. From 2012 to 2017 he served as Assistant Principal Cello with the Grand Rapids Symphony and joined the Detroit Symphony Orchestra in May of 2017.

Crosmer is the composer and arranger for the GRS Music for Health Initiative, which pairs symphonic musicians with music therapists to bring classical music to hospitals. In March of 2017, the Helen DeVos Children's Hospital launched a music channel that runs continuously, using four hours of meditative music composed by Crosmer and performed by musicians of the GRS.

Crosmer is a founding member of the modern music ensemble Latitude 49. He is also a current member of the band ESME—a duo that aims to broaden the education of classical music by bringing crossovers and mashups of pop and classical music to schools throughout Michigan. ESME released its first CD in December of 2016.

In April of 2013, Crosmer toured London with the Grand Valley State University Chamber Orchestra performing the Boccherini G Major Concerto, No. 7. He performed the Vivaldi Double Concerto with Alicia Eppinga and the GRS in March of 2016. While still in school, Crosmer was awarded the prestigious Theodore Presser Graduate Music Award to publish, record, and perform his Crosmer-Popper duets. He recorded the duets with Julie Albers, and both sheet music and CD recordings are available online.

Crosmer has taught music theory, pre-calculus, and cello at universities across Michigan. He draws mazes, writes science fiction, and plays good old country fiddle in his spare time.
