Yes, but ask your teacher first. They usually have a sequence in mind, and changing books midway can leave gaps.

Which book is best for adults?

Many series have an adult edition. They move faster and use pieces with grown-up appeal. Ask your teacher which they use.

Are digital pianos fine for lesson books?

Yes, especially a model with weighted keys, so the feel is closer to an acoustic piano.

Faber, Alfred, Bastien or RCM: which piano lesson book is yours?

If you have a piano teacher, there's a good chance your book comes from one of four series. They all teach the same fundamentals (reading notes, rhythm, hand positions). They just take different routes.

LessonKeys isn't affiliated with any of these publishers. This is a plain-language guide to what each tends to be like.

Faber Piano Adventures

Often chosen for a clear, step-by-step path and pieces that sound good early. They tend to be short, with titles that stick, which helps younger students.

Alfred's Basic Piano Library

One of the most widely used series. Methodical, with plenty of theory and a gradual move through hand positions.

Bastien

Known for a careful, slow build, with lots of repetition of each new idea before moving on. Good if you like to feel solid before the next step.

Royal Conservatory of Music (RCM)

Used heavily in Canada and tied to graded exams. Pieces are chosen to prepare you for each grade, and the technical requirements are specific.

Which one is best?

Usually the one your teacher's already using. A good teacher adapts to the student, so the book is a tool, not the lesson.

Can I practise from these with an app?

What matters is that you can read the page and play it. LessonKeys is built around the page your teacher assigned, so you can practise it between lessons and see every wrong note as you play.
