When I was taking lessons, my tutor and I aimed to meet up once a week, but it often ended up as once every two weeks. It will depend on your workload (as in day job), your own learning pace and also on the quantity of new stuff to learn in each lesson. Each of my lessons contained some theory and at least one (real) song which applied the theory, but more often there were two real songs. I was pretty crap on the practical side, i.e. actually playing the songs, but very good on theory, reading notation, and swotty things like that
