Following the foregoing rapid report, steady vibrations of a bowed string are studied as self-excited maintained vibrations in a piecewise-linear continuous system. The effect of torsional compliance in relation to the condition of capture of the string by the bow is also discussed. The piecewise-linear model is valid for vibrations of two-step zig-zag type, since the return velocity of the bowed point in them is almost exactly constant. This is a introductory trial for constructing an a priori theory of selfexited maintained vibrations of a bowed string. Errors due to any small deviation of the return velocity from the constant one may be corrected by means of one of small parameter methods, which starts from the obtained piecwise-linear solution as a generating solution.
