Meetings The Brazilian Association of Organists was created in Mariana. National and Latin American meetings of organists and organ makers, as well as interpretation workshops and festivals like the All the Keyboards (Todos os Teclados) take place in the city.

In July 2002, the Third Keyboard Week was held as part of the Mariana and Ouro Preto Winter Festival. Courses, talks, and concerts provided the public with a unique opportunity of seeing, comparing, and getting information about different keyboard instruments. Parallel to this event, Mariana housed the Twelfth National Meeting of Organists, promoted by the Brazilian Association of Organists.

From July 11–17, 2004, Mariana housed the Fourth Keyboard Week – All Keyboards, bringing together harpsichord, organ, fortepiano, and clavichord players, promoting an event at the same time artistic and scientific. With activities including talks, courses, and conferences by researchers and instrument players from Brazil and abroad, specializing in various kinds of keyboards, the climax of the event for the population was the series of concerts played on instruments from different historical contexts, which provided a true time travel through sounds.
