The student wants to improve their singing range and diction. For range, they intend to do exercises like "macaroni ravioli" to strengthen their vocal cords and allow them to sing higher notes. This will help widen their range from their current lowest of F3 to highest of G5. For diction, they need to maintain a round, open mouth shape to clearly enunciate words while singing and prevent slurring. Exercises like "AEIOU" in staccato and longatto will improve diction by forcing precise vowel sounds and lowering the jaw.
