SEÁN MATTHEW DEIBLER
IN MEMORIAM

A native of Bryn Mawr, Pennsylvania, Seán Matthew Deibler received his degree in clarinet and voice from Susquehanna University in 1969. After graduating, he was hired by The Haverford School, a private K-12 boys’ school just outside Philadelphia, and was given charge of the Lower School (K-6) music program. During that summer he attended a seminar at the Dana School of Music in Wellesley, MA which introduced him to the Kodály concept of music education. Seán was completely inspired by the course and over the next five years completely rebuilt Haverford’s Lower School music program.

In 1970 the Kodály Musical Training Institute opened its doors; and instead of holding its own summer course, encouraged all interested parties to attend the first international Kodály Seminárium in Kecskemét, Hungary. Seán attended and received much acclaim from the faculty. He returned to summer courses in the US and Hungary and in 1973 joined the faculty of the Kodály Music Training Institute teaching solfège, voice and chamber music at its summer course on the campus of Wellesley College. He remained on KMTI’s faculty and later that of the Kodály Center of America for many years.

By the summer of 1974, Seán’s work at Haverford had grown and blossomed. The “petals,” so to speak, included a nationally known boy choir that included students from all grades (even a Junior!) with unchanged voices. Every student in the Lower School had music twice a week and a pilot class was formed that had Music as a core subject, meeting every day. Seán was rightly proud of his accomplishments and had shared his wisdom and work with hundreds of summer course students, but he felt a strong urge to improve his own skills and to reach higher levels of musicianship and performance.

In the spring of 1974, he was accepted by the Liszt Ferenc Académia in Budapest and began studies in September. In spite of the added hurdles of the Hungarian language and cramming five years of study into one, Seán earned the Liszt Academy diploma in conducting, chamber music, clarinet and voice. In addition he toured Europe with pianist Katalin Komlós as both clarinet and baritone soloist.

In 1975, he returned to the US and continued his work at Haverford. By 1984 The Haverford School Boychoir was internationally known for its performance of the most challenging literature for treble voices including opera. The Kodály-inspired music program at Haverford had grown to encompass grades K-12. Seán had been made head of the music department and had played a major roll in the design of a state-of -the-art performing and visual arts center on Haverford’s campus. It boasted a six hundred seat opera house/theater/auditorium, facilities for classroom, choral and instrumental teaching/rehearsal and practice rooms, as well as dedicated facilities for the teaching and display of visual arts. To this day it rates among the finest performance venues in the Greater Philadelphia region.

 In 1978, Seán , with colleague Bill Gatti, established The Music Group of Philadelphia. The ensemble rapidly became a strong and influential presence among Philadelphia’s many choral ensembles. It has commissioned many new works and introduced many beautiful and important seldom performed works, particularly from Eastern Europe, to American audiences. In addition to regular season in the Philadelphia area, the Music Group has also performed in New York, Allentown, PA and, in 1989 made a triumphal tour of Central Europe, including several performances in Hungary.

In 1982, Seán was named founding artistic director of the 180-voice Choral Arts Society of Philadelphia, which focused on symphonic choral literature, and became a frequent guest ensemble with the Philadelphia Orchestra. This led to three compact discs in which the Philadelphia Orchestra collaborated with the Choral Arts Society under conductors Riccardo Muti and Charles Dutoit and with mezzo soprano Jessye Norman.

Throughout his professional life Seán maintained a highly successful reputation as a guest conductor of orchestras, choruses and opera as well as performing as a clarinet and baritone soloist in North America, Europe and Australia. In the summer 1986 he made his London debut at Royal Festival Hall, as well as his Warsaw and Berlin debuts with Choral Arts and the Warsaw Symphony conducting Vaughan Williams' Symphony No.1. He remained active and in demand in these activities well into the new century.

In March 1998, Seán received the Medal Pro Artibus, Artist of Outstanding Merit for Promotion of Diversified Hungarian Music Abroad, by the Ministry of Cultural Arts of the Republic of Hungary and the Board of Artisjus. He served for more than a decade as both conductor and jurist for the VIVACE International Choral Festival in Veszprém, Hungary. On his 10th anniversary as a conductor in residence he was awarded that city’s Gold Medal of Honor. In 2001 he received an Honorary Doctorate of Fine Arts from Susquehanna University. In 2008, on the 30th anniversary of The Music Group of Philadelphia, both he and the chorus were recognized by the Mayor Nutter for their outstanding contributions to the musical life of Philadelphia.

Perhaps the most remarkable achievement among these many successes is the many hearts and spirits Seán touched, nurtured and inspired. As so many have acknowledged, he had a life changing influence on all he encountered through his consummate musicianship, love of people and his passion for life and friendship. In yet another of his many talents, composition, you will hear today much of the same spiritual encouragement that he lavished on those who would listen, sing and play.

Today, we celebrate the life of Seán Matthew Deibler: a life lived to the fullest, one dedicated to spirituality and to the great healing, uplifting and aesthetic power of music. Requiescat in pace!
