Harrison organs stand firmly in the English musical tradition.  Their distinctive sound is based on 150 years of experience and development.  Meticulous standards of design and construction have ensured that H&H organs have a reputation for longevity.  In a series of high-profile restorations, we have demonstrated our ability to enter into the spirit of organ builders of different periods and styles.
