Sra. Alicia and Susana review the difference between voz alta (high voice) and voz baja (low voice.) Sra. Alicia continues to review the terms alta (high) and baja (low) using a TPR activity; whenever a high voice is used the hands of the students go up, and whenever a low voice is used the hands go down. Sr. Modesto joins Sra. Alicia and we learn about el xilófono (the xylophone), demonstrating that the small keys in the xylophone have sonidos altos (high sounds) and the large keys in the xylophone have sonidos bajos (low sounds).
