Practising your 'musical memory' might help a little?

I was taught ages ago, that the brain often likes to 'round up' or resolve in your memory a sequence of notes, which don't feel satisfying or familiar.

So deliberatley having someone play you a sequence of notes, which includes 'unsatisfying' elements (like a semi-tone where the brain wants to hear a full tone) and then singing that exact same sequence of notes back from memory, will help you hear where your brain is a little lazy, and with practice help you learn to reduce that slippage.

I have a horrid feeling that I've not explained myself well here at all, but maybe someone else will know what I mean, and can express it better!
