AB  - The non linear behavior of the piano strings is a very important issue when the chords have to be recognized using spectral patterns. In order to calculate the pattern and masks used in the recognition algorithm it is necessary to model the effects of non linearity. A model using intermodulation products have proved to give good results. For validation of the model we have recorded 11 pianos and analyzed the ?A? note of the octaves 1 to 7, using 4 different forces. The basis of this model are presented in this contribution.
