You can select a key (hover over its name, e.g. c1). If you would like to adopt a pipe, please send the appropriate amount to the collection's transparent account IBAN: CZ30 0100 0001 2378 0962 0257, SWIFT: KOMBCZPP and write the name of the pipe and the rank (e.g. c1, Principal 4 HW or D, Principal 4 HW , etc.) and your name in the purpose of payment/message to the recipient, if you agree to let us publish it for the respective pipe. Principal is the basic register of the organ and its pipes form the main dominating feature of the organ visible to the listener.
