Playing with six hands means: voluminous sound in all registers, higher density and harmonic variety of chords without stepping beyond a moderate grade of difficulty in the individual parts. It also means fun for three, practising time-keeping and physical co-ordination as well as working together in a group, exchanging ideas, listening to and fitting in with others. Besides, it is also an excellent way of fitting large numbers of pupils into one recital.
