Using the octave chromatic division (21-12) and the difference between two tones (22-12 - 21-12), the authors define alpha and beta in Pollen's parametric equations to calculate new wavelet coefficients. First four coefficients were calculated using alpha = 21-12 and beta = 0, then alpha = 21-12 and beta = 22-12 - 21-12 were calculated for the definition of six coefficients. This paper describes the calculations and shows the results yielded in the direct and inverse transform of musical signals.
