If you’re a jazz fan, opening a jazz cash account is a great way to support your favorite musicians and bands. Jazz accounts are open to anyone who is 18 or older and has an American Express card. To open an account, you’ll need to provide your name, address, and credit card number. You’ll also need to provide your musical preferences and the amount of money you want to invest in jazz music. Once you’ve filled out all the necessary information, you’ll be able to access your account and start investing in jazz music!
