The four tones in Chinese represent variations in pitch. This lesson will introduce a special approach to aid pronunciation: head-hand method. Based on the coordination of the head and the hand, the third-degree tone, one of the 5 pitches in the Chinese language, is produced and the pitch range properly set, and accuracy in the pronunciation of the four tones is therefore achieved. Also examples are used to illustrate the features of T3 Sandhi to assist learners in overcoming off-key T3 Sandhi and in improving accuracy and fluency in expression.
