One possible idea could be getting your granddaughter a set of high-quality blues music CDs or vinyl records from popular artists in the genre. You could also consider getting her concert tickets to see a popular blues musician live in concert, or even arranging for her to take music lessons to further explore the genre herself. Another option could be booking her a stay at a blues-themed hotel or vacation rental in a city known for its blues music scene--such as New Orleans, Memphis, or Chicago--so she can immerse herself in the culture and really indulge her love for the music.
Or you can get her a star map with the date when she was born.
