I am fostering a lesser sulphur crested. Her favorite is Ralph Vaughn Williams "Variations on a Theme of Thomas Tallis." It is ravishing. She also likes his "The Lark Ascending" as well as the Bach Badinerie and some Mozart. She can whistle a bit from Mozart's " Queen of the Night" aria from "The Magic Flute."
I have also played some popular music for her, such as Pharrell Williams' "Happy." but it doesn't make her as relaxed and happy.
I want her to be relaxed and happy above all. So I will continue to explore among similar sounds to which she responds well.
