New sound processing tools can give new possibilities in analysis of musical structures, modeling of an instrument's characteristics and musical pattern recognition.This paper presents an efficient method for recognizing isolated musical patterns played by Greek Traditional Clarinet, in a monophonic environment.A moving window technique is applied to the input signal.From each frame a frequency is selected which corresponds to a certain Fourier peak.The extracted sequence of frequencies is in turn treated as a signal.The logarithm of the above signal is calculated and the resulting signal is given as input to a recognizer which employs standard Dynamic Time Warping Techniques in order to determine the input pattern.A recognition rate higher that 98% is achieved by our method.
