Unconventional decks like having anki cards for a whole piano piece or problem in a textbook might work
I have used Anki for learning bass guitar parts to songs, and I found this method: break a piece up into individual riffs or themes, make flashcards with the "[name of song] [riff or theme sheet music / tablature]". Add in flashcards that use cloze deletion on a list of how the riffs progress (intro -> verse -> ... -> verse -> chorus -> coda, for example, deleting chorus) and you have 10-20 cards, depending on complexity. I also threw in transitional licks appropriate to the song to bump the count up.
When testing yourself with the deck, have your instrument at hand. On riff cards, practice the riff for five minutes, then hit 'again'. Answer the other cards as normal - I originally planned to play the riff that was deleted, but I found it wasn't really necessary. I suggest responding 'again' to each riff card until you can play the riff first try.
The bonus of this method is it works out to ~1 hour of practice of your instrument. I found huge improvements because it ensured 80% of my hour was spent actually learning and improving rather than practicing well-known or ingrained patterns. My recall of songs from name was significantly higher too.
Thank you! I was planning on setting up a system for piano and guitar and I wasn't really sure what would work. This sounds great =]

I've updated my Anki database for the Less Wrong Sequences to include cards from A Human's Guide to Words. I've been trying to put less information on each card, and I relied on cloze deletion more for the newer ones. Feedback is much appreciated. You can download them by opening up Anki, going to Download > Shared Deck and searching for Less Wrong Sequences.
I probably erred on the side of making way too many cards, but it seemed really important to me to internalize this stuff, since I think it has quite a lot of practical value. I can tell learning this deck has improved the quality of my thinking and my conversations with people because I'm better at noticing when I'm making one of the 37 mistakes and changing my course. I hope other people find it useful too!
