When you look inside an organ you will see many pipes in a variety of shapes and sizes.

An organ with about 16 stops usually has more than 1000 pipes. A cathedral organ may have 10,000 pipes.

However large or small an organ is, its pipes may be grouped into five main families:

• DIAPASONS• FLUTES• REEDS• STRINGS• MIXTURES

DIAPASON family

These pipes are usually seen on the front of the organ.

The tone is bold and full.

Children and the Organ Project

The project aims to introduce young children to the fascinating world of pipe organs through practical workshops and fun

activities. The building and playing of organs being such multi-disciplinary activities, their study has numerous spin-offs for the

school curriculum.
