North Indian Classical Music also known as \Hindustani Classical Music" is one of the oldest music cultures still being performed actively. Although the technologies related to Music analysis have taken a giant leap over the past few years, not much has been researched related to the expressiveness of Hindustani Classical Music.

In the current work, we have tried to analyze & classify the four major types of ornaments present in the Hindustani music viz. Kan, Meend, Andolan and Gamak based on the micro variations of the pitch information of Hindustani Music. The choice of research based on the pitch data was made because of the fact that Hindustani music is primarily monophonic and melody based, as such the \Time Series" analyses techniques could be applied to the pitch data for analysis of Hindustani Music.

AutoCorrelation Function and Dynamic Time Warping has been used to classify the four different ornaments. Kan-Meend vs. Andolan-Gamak has been classified with a success rate of 88.7% while Kan vs. Meend with 85.4% and Andolan vs. Gamak with 86.8%

Apart from the methodology for analyzing & classifying the ornaments described in the current text, while undertaking the current work, a new method to correct "Octave Errors" in Hindustani Music was also developed.
