How can I effectively use spaced repetition for memorizing and retaining musical notes and chord progressions as a beginner pianist?

I totally get where you're coming from - it can be tough to retain all the notes and chord progressions when you're just starting out. I've heard that spaced repetition can be a game-changer, but like you, I've tried a few different methods and wasn't seeing the results I wanted. One thing that's worked for me is to set a specific schedule for reviewing my notes and chord progressions. For example, I review the notes I learned yesterday, then the day before that, and so on, with increasing intervals in between. It's been helpful to keep track of what I need to review and when using a planner or a note-taking app.

As for the frequency of repetition, I've found that it's not about reviewing something every day, but rather at optimal intervals. So, if you learned a new chord progression last week, you might review it today, then again in a week, and so on. It's also been helpful for me to review notes and chord progressions that I'm struggling with more frequently, and to move on to new material when I feel more confident. I've also found that incorporating active recall into my practice routine - like playing a piece from memory or improvising over a chord progression - really helps solidify what I've learned.

I've used a few different tools to implement spaced repetition in my practice routine, including flashcard apps like Anki, and note-taking apps like Evernote. I've also found it helpful to create a review schedule and stick to it. One thing that's worked for me is to set a specific time each day to review my notes and chord progressions - whether it's first thing in the morning, right before bed, or during my lunch break. It's also been helpful to review my progress and adjust my schedule as needed. I've also found it helpful to get accountability from a study group or a practice buddy - having someone to review with and stay motivated really helps.

As for resources, I'd recommend checking out the Anki app, which has a built-in spaced repetition algorithm that can help you optimize your review schedule. I've also found it helpful to use online resources like practice exercises and video lessons to supplement my practice routine and stay motivated. And finally, don't be afraid to reach out to your teacher or a more experienced musician for advice and support - they can provide you with valuable insights and help you stay on track.
