 The Pipe Organ
How it works...
…the pipe organ is a big box of whistles. Each pipe sits on top of a hollow wind chest that is filled with compressed air provided by a bellows or blower. Each ‘stop’ at the organ console represents a set of pipes (a rank) of a particular tone color, with a different pipe for every note on the keyboard. Pulling the stop activates a slider under that specific set of pipes on the windchest, making them available as a sound-source. The wind chest also contains a series of valves (pallets) connected to the keyboard by a mechanical linkage. These pallets govern the flow of air to each pipe, and even though a stop may be on, no pipes will sound until a key is depressed and its respective pallet opens. This allows the compressed air to pass up through the pipe for that note, creating sound.

The intermanual coupler functions in the Dutch manner: the Werk couples to the Rückpositiv. This is particulary useful in leading hymn singing. The accompaniment can be played on the Werk, and its stops combined with those of the Rückpositiv play the choral tune.
Historical Clarinet
I play a historical clarinet based on a twelve-key model by Grenser from 1812 built by Rudolf Tutz, Inssbruck Austria. The instrument has a warm charming tone, not quite as strong as the modern clarinets, but allows more flexibility in the tone and articulation.
