Thoughts on Harry Gensler’s Introduction to Logic?

[uganns119]

I’d like to start learning some basics of logic since I went to a music school and never did, but it seems that he uses a very different notation system as what I’ve seen people online using. Is it a good place to start? Or is there a better and/or more standard text to work with? I’ve worked through some already and am doing pretty well, but the notation is totally different from classical notation and I’m afraid I’ll get lost and won’t be able to use online resources to get help due to the difference.
