dc.description.abstract	Pitch training is an important exercise for classical singers. This paper presents a Visual Feedback Technology (VFT) time system to improve pitch tuning. The objective is to present the developed helpful tool that allows in a didactic way to tune the voice and show the user the error due to the comparison between the voice produced and the target frequency of the notes along the melody. The voice signal acquisition system and fundamental frequency fo detection uses the autocorrelation method with center-clipping and compares it with the frequency of each note in different applications. The system allows the training using ascending or descending sequential notes, allows the training with a pre-existing melody, and allows to build of a new melody. It permits the identification of the adequate scale for the practitioner and the selection of the adequate scale for each practitioner. As for the results evaluation, the pitch training evolution of an experienced singer and another person without singing experience evidences the efficiency of the Voice Tuning System. The system was also evaluated by a questionary with all heuristics in the first upper quartile.	pt_PT
