For the first few weeks, only about 10 to 15 minutes a day. As your repertoire (the number of songs you know) grows, your practice time will increase, possibly to 20-30 minutes daily for the first several months. It’s pretty common for students to enjoy practicing so much that they lose track of time, though!
There are 3 investments: tuition, online materials, annual registration. The online materials are registered and paid for online. All other payments are made to the studio/teacher.
Check, cash and credit card (coming spring 2019)
