The Historical Keyboard Society of North America is a United States-based non-profit organization comprised of members who love and promote early keyboard instruments. Formed in 2012 by the merger of the Midwestern Historical Keyboard Society (MHKS) and the Southeastern Historical Keyboard Society (SEHKS), its members include instrument builders, players, teachers, and scholars, as well as many who merely love the looks and sounds of these beautiful instruments.

Western Early Keyboard Association (WEKA) was founded in 1998 to promote mutual interests, foster communication, and share resources and expertise among harpsichord, clavichord, fortepiano, and organ enthusiasts, both professional and amateur, in the western United States.

The Piano Technician's Guild is the world's premier source of expertise in piano service and technology. We represent more than 100 years of collective knowledge, over 4,000 global members and the industry's only recognized piano service certification program, the Registered Piano Technician.

Master Piano Technicians of America is a place for technicians to find out about the MPT and its members, as well as to find ways to exchange their ideas, practices, and experiences in the field. Be sure to watch for details on our upcoming convention, an event I look forward to every year. The best of the best in our group share their expertise, warmth, and wit; and we all take advantage of an opportunity to socialize with “MPT family” for a few days. Not only can the technician benefit from this site; the piano owner can also use it to find MPT technicians and learn about the instrument. I invite everyone to participate and enjoy.

The BHS focuses on plucked keyboard instruments, Harpsichords, Spinets and Virginals. Our website is intended to complement existing harpsichord resources with both original material and links to other sources of information.

OHS membership has grown since 1956 from that small group to an international society of musicians, organbuilders, historians, scholars, and music lovers. The founders of OHS aspired to visit extant American “tracker” organs, create a comprehensive list with specifications, and share information with interested organ scholars. The OHS has far exceeded this aspiration in the six decades since, having created an online database of pipe organs with more than 60,000 entries; a historic organ citation program that has recognized more than 400 instruments; the world’s largest collection of pipe organ-related archives, books, journals, pamphlets, and other ephemera; annual conventions that take place in locations around the country; publications including a quarterly journal and award-winning scholarly books on the pipe organ; and an online store with organ-related books, CDs, videos, and sheet music.

The mission of the American Guild of Organists is to foster a thriving community of musicians who share their knowledge and inspire passion for the organ. The vision of the American Guild of Organists is to engage, support, and uplift every organist.

The ISO has more than 280 member firms fall over the world. The Society stands for quality in organ building, and recognizes and welcomes diversity in organ building styles and philosophies worldwide. Founded in 1957, the ISO aims to promote communication, cooperation, friendship, and sharing of information among all those who are engaged in building pipe organs.
