A system that is capable of identifying all the elements in a polyphonic piano recording which are necessary to write out the score, using a record of the musical piece, is presented in this contribution. A piano piece is processed and analysed using wavelet filters and the discrete Fourier transform, the correlation properties among the different harmonics of the sounds are also used to identify its rhythm and sound. By this means, the system designed identifies the different notes that were played, their attack instant, span and intensity. An analysis if these results allows to estimate the key signature, tonality, tempo and time signature of the piece
