The cinema organ is put through its paces - it can make the sound of a dog barking and bells ringing etc.
M/S of the famous Scottish organist Mr R.O. Pagan sitting at the organ. He plays the end of a piece of music.
C/U of Mr Pagan, he speaks directly to camera. "Ladies and Gentlemen. I hope that by now you will have heard, the cinema organ in its coat of many colours is fundamentally an organ. Now I should like you to hear, in the novelty section of the cinema organ, a brief version of "The Whistler and his Dog". C/U of his hands as he plays. It is a rather jolly tune with part that sounds like a dog barking. It is quite silly and funny. "Chimes, for a change." C/Us of small church bells being rung. We cut back to Mr Pagan and realise that the sounds of the bells are coming from his cinema organ. It sounds very realistic. "Ever been in a Clyde shipyard? This is how it sounds." Mr Pagan makes shipbuilding noises with his organ. Shots of large ships in the shipyard are intercut with shots of the organist.
"Every instrument is possible on the cinema organ. This elaborate syncopation shows you a few." Mr Pagan puts his organ through its paces.
