2020 national convention planned for July in Atlanta, Georgia, was cancelled due to the COVID-19 pandemic. The AGO sponsors a number of education programs, including "Pipe Organ Encounters", which are intended to introduce youth to the organ and its workings. It also produces a series of instructional DVDs for organists, providing insights into advanced playing technique, organ registration, improvisation, and interpretation. Renowned organists on these Master Series videos are: Catharine Crozier (vol. 1), Marie-Claire Alain (vol. 2), Frederick Swann (vol. 3), Gerre Hancock (vol. 4), and Marilyn Mason (vol. 5). The AGO issues several professional certificates and designations upon completion of the appropriate exams and membership in good standing: the Service Playing Certificate (SPC), Colleague (CAGO), Choir Master (ChM), Associateship (AAGO), and Fellowship (FAGO), the highest level of certification bestowed upon accomplished organists by the organization's Board of Examiners. The American Organist Until November 1967, the journal The Diapason (published by Scranton-Gillette) was billed as the Official Journal of the American Guild of Organists, and the Official Magazine of the Royal Canadian College of Organists. In 1967, the AGO began publishing Music Magazine, a news journal for its membership. Now titled The American Organist, the monthly magazine is the official journal of the AGO for members and non-member subscribers. The illustrated periodical features news about new and restored pipe organs, concert programs, research into organ literature, chapter activities, and reviews of new organ recordings. The American Organist is also the official magazine for the Associated Pipe Organ Builders of America. Its masthead proclaims the journal's goal, to further the AGO's "ideals, objectives, and cultural and educational aspirations". From October, 1968, to June, 2009, The American Organist was also the official journal of the Royal Canadian College of Organists. The AGO also is an affiliate with the online journal Vox Humana. Contests The AGO organizes several awards and competitions, including the Pogorzelski-Yankee Competition, the AGO/ECS Publishing Award in Choral Composition, and the AGO/Marilyn Mason Award in Organ Composition. The AGO/Marilyn Mason Award has its roots in the Holtkamp Organ Composition Contest, which was inaugurated in 1978 by Walter Holtkamp (president of the Holtkamp Organ Company) and Donald Hinshaw (president of Hinshaw Music) to encourage composers under 30 years of age. The Holtkamp Organ Composition was held annually until 1984 in conjunction with the International Contemporary Organ Music Festival at the Hartt School of Music.
