Charles Callahan is a native of Cambridge, Massachusetts and is well known as an award-winning composer, organist, choral conductor and pianist. His education was at the Curtis Institute of Music and the Catholic University of America.
Callahan's Aria, published in 1988 is a perfect example of the composer's gift for a hauntingly beautiful melody. The piece begins in e-minor and soon transitions to E-major as the crescendo begins. I have used the many sensuous string stops of the Walcker organ to build up the ensemble to a rather robust forte. I've made one or two slight modifications to the printed registrations in the score and I hope Dr. Callahan would approve.
