Pitched instruments are those that have a well-defined pitch or fundamental frequency-in this case, normally the "pitch"(a subjective frequency measure) matches the "fundamental frequency"(an objective frequency measure). For that reason, it is common that both terms be used interchangeably. Most pitched instruments are also harmonic, meaning that their partials... are close to being harmonics... However, some percussion instruments have a defined pitch, but their partials tend to be nonharmonic.  1, fiche 1, Anglais, - pitched%20instrument

... it is quite natural to look at GSPD as a fractal measure... with infinitely many types of singularities. Probing the surface with many random walks is equivalent to the estimation of the corresponding solutions of Laplace's equation... which are usually called harmonic functions. Consequently, the name harmonic measure is also used for GSPD.  2, fiche 3, Anglais, - harmonic%20function

To calculate the harmonic measure and its characteristic properties one can follow two numerical methods. i) After having generated a DLA cluster one releases further particles... whose diffusional motion is simulated by the same technique... which is used for growing the aggregate. These probe particles, however, are eliminated when they arrive at the surface, and a record is kept of how many times each of the surface sites is contacted in this way. The normalized number of contacts is then regarded as the growth probability.  2, fiche 3, Anglais, - harmonic%20function

DLA and the Harmonic Measure. How can we best characterise the surface or perimeter of... fractal structures? The harmonic measure affords a method of quantitatively characterising such surfaces. This(probability) measure is defined(with respect to a particular cluster) as the probability,... of a random walker approaching the cluster from infinity first striking the cluster between the points... along the boundary of the cluster.  1, fiche 5, Anglais, - probability%20measure
