Analogique A (1958) for 9 strings was dedicated to Fred Goldbeck. It is a practical application of Stochastic Music. The Sounds are chosen statistically in arbitrary ranges of frequency, intensity, and density. These ranges change in accordance with the transitional probabilities which follow a series of consequential events (the Markov series). The probabilities make up linked matrices in which the balanced entities are adjacent. They are linked at their limits. The result is a series of 8 linked 'sound states' which derive their order from a similar but more general Markovian series which is biased towards stability. This series is however subjected to the influence of certain random variations. By virtue of its construction the sound mechanism reverts from these to its balanced state. The work was created by Andrew Girard at the 1960 research festival.

Analogique B (1959) was dedicated to Olivier Messiaen and is constructed in a like manner to Analogique A except for the introduction of a sentimentality hypothesis that all sound is made up of small bodies. Thus a 'grain' of sound can be defined approximately as a sound sinusoidal in form and of given intensity which has a duration of the order of the 'thickness' present.

Analogiques A and B for strings and sinusoidal sounds are shown to be two like entities which can be compared to each other within the framework of cybernetics.
