Greek letters have simpler vocalisations than "c4" or whatever, though?! This relates to internal vocalisation, a subject on HN a couple of times recently, as I don't really do that (particularly for equations) then it was never an issue for me. Though at 15 I learnt the Greek alphabet as I was into physics, that probably helped. People who need to vocalise to read, and don't bother learning (or coming up with) a vocalisation are going to find it very difficult.
