About Rose

Rose Winstanley-Trefz has been tuning pianos since 1976.

Rose began her career tuning pianos while in the eleventh grade at Waterford Mott High School, in Waterford, Michigan. She was studying with an exceptional choral director who gave a lecture one day on piano tuning. Rose knew at that moment tuning pianos was what she wanted to do for her career.

Rose apprenticed with John Quitmeyer, owner of the Piano Shoppe in Rochester, Michigan. By the time she graduated from high school, Rose was busy tuning pianos in private homes, and in a short time had expanded her business greatly. Rose began work as an independent contractor with the Steinway/Yamaha piano store, Hammell Music in Livonia, MI in 1979, and Melody Hut the local Kawai Piano dealer. Rose also received training and became manufacturer certified by attending Yamaha Piano’s Little Red Schoolhouse located in California and Kimball Piano School in Indiana.

One of Rose’s early career goals was to be a concert technician for a local outdoor music theater, Pine Knob Music Theater, in Clarkston MI, where she attended concerts from the age of thirteen-years-old. By the age of twenty, Rose was tuning for such famous groups as: The Moody Blues, Journey, Allman Brothers Band, Lionel Richie, Bette Midler, Pat Benatar, Peter Frampton, Donna Summer and many others.

Being very active with the Piano Technician’s Guild Detroit/Windsor chapter, Rose attended a Piano Technician Guild conference in 1986 and met her future husband John Trefz, who is fifth generation in the piano business. Rose and John’s was a case of love at first sight. She moved to Pennsylvania in 1987 and was hired to do concert and in-store tuning for Jacob’s Music, the Steinway/Yamaha dealer in Philadelphia. Rose enjoyed having the opportunity to tune pianos is some of Philadelphia’s most historic and prestigious places, such as the Academy of Music, Philadelphia Museum of Art, Franklin Institute and the Belleview-Stratford Hotel. In 1989, Rose left Jacobs Music and for a year became an independent contractor for Wilmington Piano Company.

Rose not only tunes by ear, she incorporates the latest piano tuning technology, the Sanderson Accu-Tuner, which is used by the Piano Technician’s Guild for their standardized tuning tests. Her goal is to do the most thorough, stabilizing piano tuning possible for her clients.

Rose is very grateful for her wonderful clientele! Rose tunes pianos in private homes around Southern Delco. Rose’s many clients include Darlington Fine Arts, Rose Tree Park (outdoor concerts), Swarthmore College, Wallingford Arts Center, Springfield Music Store
