Organ (music)

Organs were a type of keyboard instrument.

After the Sixth Doctor repaired his TARDIS' chameleon circuit, it took on the form of an organ for some time. The Doctor played the opening of J. S. Bach's "Toccata and Fugue in B Minor" on it. (DW: Attack of the Cybermen)

The Tenth Doctor amplified the noise of Southwark Cathedral's organ with his sonic screwdriver. The noise distracted Richard Lazarus who then fell from the tower and died. (DW: The Lazarus Experiment)

When an Aeolian travelled to Earth, she went to the High Cross Cathedral to call for her mate, causing storms across the United Kingdom. K9 Mark 2 and Starkey tracked her down and after she was stunned by CCPCs, Starkey played a tune he'd been humming recently on the organ, succeeding in contacting her mate, the two Aeolians then left Earth.
