Good friends and colleagues, Janet Tebbel and Lisa Lonie have been performing off and on as a duo team since the early 1990s. They are recognized soloists on their own, with decades of combined artistic and teaching experience with the carillon.  

As the Treblemakers traveling duet carillonneurs, they have appeared in many carillon festivals and summer series throughout North America and Europe. Most notably, in 2014 they represented the North American Guild of Carillonneurs (GCNA) at the World Carillon Federation congress in Antwerp and Bruges, Belgium. Thereafter, they embarked on a one-week tour of The Netherlands, performing on a variety of modern and historical carillons, one of which dated to 1659. In March 2017, they participated in the International Carillon Festival, Bok Tower Gardens, Florida—one of the most prestigious week-long carillon recitals in the world.  
Janet Tebbel is the carillonneur of two carillons in the historic Germantown section of Philadelphia. She has served as carillonneur of the First United Methodist Church of Germantown, playing the 50 bell Taylor carillon since 1979; and has also been the carillonneur of the Miraculous Medal Shrine, with a 47 bell Paccard/Bigelow carillon, since 2002.

Tebbel began her carillon studies with R. Hudson Ladd at the University of Michigan and continued to play at the University of Rochester, New York while earning a master’s degree in organ at the Eastman School of Music. With a grant from the Belgian-American Educational Foundation, she spent a year at the Royal Carillon School in Mechelen, Belgium, studying with Piet van den Broek, and earned a final diploma from the school.
Lisa Lonie is the carillonneur of Princeton University, as well as at St. Thomas' Church in Whitemarsh, Pennsylvania, and at the oldest carillon (1882) in North America located at the Church of the Holy Trinity (Rittenhouse Square) in Philadelphia. Privately, she commissions new works for carillon which have added to the rich portfolio of carillon compositions in North America.

She is a carillonneur member of the GCNA, former chair of the Examinations Committee, and has served on its Board of Directors and on a variety of committees. Lonie began her carillon studies as a teenager with Frank Law, carillonneur at the Washington Memorial National Carillon in Valley Forge, Pennsylvania and continued with Frank DellaPenna, Mr. Law’s successor.

Lonie is a graduate of Pennsylvania State University with dual degrees in German and economics.  Besides her musical interests, she is a mom of three, grandma of five, and resides outside Philadelphia with husband Paul and assorted wildlife.  While not climbing bell towers, she is the assistant chief of staff at Haverford College.
