is based on the Nine Lessons and Carols model developed at King's College, Cambridge from a service at Truro Cathedral in Cornwall. In addition to their primary function of supporting worship, the choirs of Trinity Church are fixtures in the rich musical landscape of Boston. The Trinity Choir has toured extensively, and can be heard on several critically acclaimed recordings. The Trinity Choristers are a group of children who learn music and sing in the tradition of the Royal School of Church Music. The current Director of Music and Organist is Colin Lynch. The Trinity Choir and Trinity Choristers tour England every three years, serving as choirs-in-residence at major houses of worship such as Ely Cathedral, Chichester Cathedral, and Westminster Abbey (summer 2016). Organs 1876: The original organ at Trinity was built by Hilborne L. Roosevelt in 1876, his Opus 29. It had mechanical action, assisted by Barker levers on all divisions and an electrically controlled Echo division, but its location in the chancel proved unsatisfactory, and the organ was moved to the gallery. 1903: Hutchings-Votey built a new instrument for the chancel and made both organs playable from a single console. 1924: Ernest M. Skinner undertook a rebuilding project, Opus 479, involving changes to both the Roosevelt and Hutchings-Votey instruments, but by 1926 it had expanded to Opus 573 as a virtually new organ in the gallery, as well as a new chancel console. 1956: Aeolian-Skinner provided a new console in 1956 and, in 1960, installed a new chancel organ. 1962: The gallery organ was extensively rebuilt, and major tonal modifications were made by Jason McKown, who maintained the organs for many years. 1987: Jack Steinkampf' installed a rank of horizontal trumpet pipes under the west gallery window. This festival trumpet is given in memory of Paul Albert Merrill. Late 1990s: In conjunction with the parish's building campaign, a plan was set out with Foley-Baker, Inc., for the cleaning and refurbishment of both organs and their joint console. Late 2010s: Since 2012, the Church has slowly acquired a stockpile of Skinner and Aeolian-Skinner pipes from the general period of Trinity’s organ. The pipes were installed and the organ reworked in an attempt to recapture the original Skinner sound. This work was a collaboration of Trinity’s former and current organ curators: Foley-Baker Inc., of Tolland, Connecticut (who renovated the nave organ in 1999-2001, and the chancel organ in 2007), and
