Suggested for beginners or intermediate level students that are teens or adults
 
One of my two go-to series for beginners or intermediate level students that are teens or adults. This series is comprehensive (the "all-in-one course" means that the book contains lesson, theory, and performance pages all in one book) and gives a complete music education. Like its series for children, the adult version is slow-paced and full of variety. An added bonus is that the book uses a lot of familiar songs to help you learn faster, which helps you feel confident about piano/ music lessons from the beginning! If you need a link to a specific book in the series, please contact me!
