If you are serious about learning, print the PDF out and put it in a binder. Piano practice requires you to look at the page and your hands simultaneously; scrolling on a tablet can be distracting.

If you’re looking for an affordable, teacher‑friendly starter book that won’t overwhelm a beginner, it’s definitely worth trying. Just be sure to obtain a legal copy (via a reputable retailer, library loan, or confirmed public‑domain source) and consider pairing it with a few modern tools to keep the learning experience fresh and engaging. Happy practicing!
