A Chunk of Chords
I've put aside So What for now and will learn chords instead, something I know almost nothing about. Chords seems like a world of knowledge unto its own. There are major chords, minors, diminished, augmented, dominant and so on. Branching out further into unknown territory is scales.
I skimmed Google Play for a good introductory app, but everything seems over my head. Luckily, Robin Hall in his Pianoforall learning system has a straight forward, shut-up-and-do-what-I-say teaching style and starts with easy C family chords. I won't get into specifics here (Pianoforall is proprietary), but I will say he uses mnemonics and chunking to good effect.
If you're unfamiliar with the chunking technique, here's an excellent article on how it can improve your memory.
