In its physiological foundations, Breithaupt's "natural piano technique" depends, in its explicit recognition, on the almost contemporary work of the physician and physiologist Friedrich Adolf Steinhausen. Breithaupt's formula "don't think about your fingers, don't want to play with your fingers" effectively summarizes the fundamental principle of the weight technique in antithesis to the digital technique. The latter prescribes the unnatural articulation of the fingers with the motionless hand and the exclusion of any arm input, from which, in addition to an unnecessary expenditure of muscle energy, stiffening, contractions and false finger extensions result. The "new" natural technique - new only as a theoretical formulation, because the great pianists have always played in this way - supports instead the need to adequately exploit the inertial weight of the whole arm from the shoulder down to the hand. The starting point is "a state of rest and complete muscular relaxation of the arm, just as we can observe it in a sleeping child or get it ourselves by letting the arm rest on the back of a chair;
The "digital game"
Despite the tendency to identify any independent movement of the fingers with stiffening and contraction of the hand and arm, Breithaupt believes that "digital play" still plays a role in piano technique and is the superior and conclusive degree of the study. This is the least convincing part of Breithaupt's treatise which appears to be divided into two parts which are difficult to reconcile: on the one hand the free play of the weight in relaxation, on the other hand the digital play which always involves a certain degree of "fixation" or muscular tension. He drew criticism of the opposite kind: that, moved by Tobias Matthay, of having considered the weight of the arm as an exclusiveelement of the technique and that, by Steinhahausen, of having reintroduced the old digital technique. Actually Breithaupt realized, with musical sensitivity and on the basis of his piano experience, the necessity of the digital game for a complete and artistic piano technique, but he was not able to justify it in a coherent way within the new approach. Steinhausen's criticism, corrected on a physiological level, did not grasp the specific piano problem intuited and not solved by Breithaupt: how to understand the digital game avoiding stiffenings and contractions of the hand and arm, i.e. the typical drawbacks of the traditional digital technique.
