The present invention relates to a method for establishing a structured timbre base with a sound wave table and, more particularly, to a method for establishing a structured timbre data file provided for data of sound waves of every kind of instrument stored in a musical synthesizer with a sound wave table to achieve an effect of reducing memory allocation and simplifying hardware complexity, having the steps of: determining a fixed total length; specifying a keynote and obtaining a plurality of sound waves according to the characteristics of different instruments to proceed recording; setting a fixed loop length; searching for a complete sampling loop wave; deleting the end portion of every timbre data file; repeating the complete sampling loop wave several times and adding to the above deleted end portion; adding a mute signal in front of every timbre data file. Therefore, a structured timbre data base is established and every timbre data file with different pitches has an identical total length and loop length.
