The Fred J. Cooper Memorial Organ Experience
The Philadelphia Orchestra has received a $5 million gift from the Wyncote Foundation to increase and expand programming for the Fred J. Cooper Memorial Organ in Verizon Hall, the world’s largest mechanical action concert hall pipe organ. The partnership is supported by longtime friend of the Orchestra and former Board member Frederick R. Haas. The five-year initiative, entitled “The Fred J. Cooper Memorial Organ Experience,” will focus on artistic plans by Music Director Yannick Nézet-Séguin, in consultation with Artistic Advisor Frederick R. Haas, to feature the organ more extensively in season programming, help to build audience interest in the instrument, and educate audiences about the organ’s musical capabilities.
The Orchestra is featuring the Fred J. Cooper Memorial Organ to showcase the majestic instrument paired with the “Philadelphia Sound.” We are elated to be enhancing our season programming to allow for works that highlight this magnificent instrument.

Rachmaninoff's Piano Concerto No. 2 marked the composer's triumphant recovery from the disastrous premiere of his First Symphony. While some elements are familiar thanks to movie soundtracks and pop songs, the Concerto as a whole is a testament to Rachmaninoff's brilliance as a composer and pianist. Haochen Zhang is a worthy interpreter of this masterwork: Not yet 30, he's renowned for dazzling technique and thoughtful interpretation. Strauss's Alpine Symphony was inspired by a trek up a mountain, from pre-dawn darkness to deepening nightfall.


The 1925 version of The Phantom of the Opera is technically a silent movie … but not when the mighty Fred J. Cooper Memorial Organ is unleashed! Verizon Hall's magnificent instrument creates the perfect soundtrack for this Hollywood classic, a tale of doomed love in the spooky confines of the Paris Opera House. Known for his performances on the legendary Wanamaker Organ, Peter Richard Conte is master of the keyboard for this special Halloween presentation.
Please note: The Philadelphia Orchestra does not perform on this concert.


Hark the herald trumpets (and horns, trombones, and tuba) sing! The unmatched sound and musicality of The Philadelphia Orchestra's legendary brass section usher in the holiday season on a high note. And the glory of the Fred J. Cooper Memorial Organ adds another heavenly voice to this collection of treasured Christmas music, with master organist Peter Richard Conte at the keyboard for this festive presentation.

Shortly after sending Handel his libretto for a new oratorio, Charles Jennens wrote to a friend, hoping that the composer “will lay out his whole genius and skill upon it.” In 24 days of feverish writing, Handel did just that, creating his immortal Messiah. Pioneering conductor and Handel expert Jane Glover brings her decades of experience with opera and Baroque music back to the Kimmel Center for our holiday presentation of this masterwork, with the Philadelphia Symphonic Choir joining the Orchestra for a revelatory performance.


What exactly is Elgar's "enigma?" We may never know but we can still enjoy these 14 charming variations on a theme that Elgar composed "to my friends pictured within." British conductor Edward Gardner, chief conductor of the Bergen Philharmonic and principal conductor designate of the London Philharmonic, makes his Philadelphia Orchestra debut, and keyboard virtuoso Paul Jacobs returns to the Fred J. Cooper Memorial Organ.

Glossary of Terms
Console
The large unit where the organist sits to play and control the organ. This includes the keyboard or manuals, pedal board, pistons, and drawknobs or stops.
Division
The pipes are grouped into several separate sections called divisions such as the Great, Swell, Solo, Positive, and Pedal. Each is controlled by its own manual or the pedal board.
Electric Key Action
In an electric key action, a wire, an electric circuit, and an electro-magnet cause the valve below each pipe to open and close. When you press the key, you close an electrical contact. Electricity flows to the circuit that causes an electro-magnet to open and close the valves under each pipe.
Mechanical Action (Tracker Action)
The key is connected to trackers (wooden, metal, or plastic strips or rods) that eventually connect to the valves that open to admit air from the wind chest into the pipe. When you press the key, you are physically opening the valve in the wind chest. In mechanical action, there is one valve for each note on the keyboard.
Note: The Verizon Hall organ has both electric and mechanical key action.
Pipes
Organ pipes fall into one of four broad sound categories: principal, flute, string, and reed. The first three types are known as "flue" pipes and work like whistles. The majority of organ pipes are flue pipes. In contrast to the whistle-like flue pipes, the reed pipes work like clarinets or saxophones, but have a brass "tongue" instead of a cane reed. Some of the reed pipes are the loudest pipes in the organ.
