Audio-demonstrations are very valuable when teaching the physics of musical sounds, and can be even more effectively used if the source is coupled to a cathode-ray oscillograph. The wave shapes can then be observed as the sounds are heard, producing an 'audio-visual-demonstration' of the physical principles involved.
These recordings show what can be achieved using entirely amateur recording equipment (for this reason the various background noises remain). The basic instrumental sounds were taken from a large collection of recordings made over a period of several years, of performances by interested students and friends.
