>it is less useful for physics, math, and music since fluency is so much important. I mean, you can put whatever you want on a flashcard. e.g "Derive the fundamental theorem of whatever", "Prove this theorem" etc. Also music has a extreme level of "stuff you just need to memorise".
Great for music vocabulary and symbols; pretty weird for learning scales and stuff. Generally best for things you need to and can answer fast, and need to know more verbally.
- What are the sharps in the key of E? (can be derived using the circle of fifths, but is better to do that with random practice until it's deeply internalized and eventually memorized, helps memorize info on the circle of fifths as well) - What is the 5 chord in the key of G? (can be generalized to all chords in all keys) - What is the relative minor of A? - What scale is A dorian (or any mode) the ionian (or any other mode) of? - What scale degrees are raised in mixolydian (or any other) mode? - What chords are 2 5 1 in (key)? - What are the chord degree numbers for an F-turn in c? - What are the chords for an f-turn in c? - What are the numerals for the andalusian (or any other) cadence?
The more I think about it, the more I think analyzing common progressions and how they often fit together via flashcards would be huge for actual in-practice musicianship as well, but I on't belabor that by adding more here. Most of these can be derived from the circle of fifths, but building the connections from repeatedly doing that over and over again is invaluable and there's so so much more you could make just reviewing the relationships there than what I have listed here.
It would also be interesting to make flashcards for practicing audiation, I can pretty easily imagine how a major, aolean, mixolydian, or harmonic minor scale sounds but am not nearly as clear on all the other ones should sound and couldn't hum them on demand.
