German cases and musical notes Anki decks

I’ve created two new Anki decks.  The first one [archived] lists German case inflections for all gender, number and article combinations.  The second one [archived] contains recordings of each of the 12 notes of the chromatic scale, in various octaves, played on the piano and as a pure sine wave; it is an experimental deck to test whether spaced repetition could help develop perfect pitch.

My other Anki decks may be found here.
