Paco makes important point ref attitude. Whilst left/right bank is pretty intuitive, pitch attitude on the AI takes a lot more interpreting and can only be done with integration with a good power/ASI/VSI scan, esp at lower speeds and on instigating climb/descent. Must say that when VFR flying I had not fully appreciated just what the AI picture looks like with the pitch change during these transition phases. Interesting and worth becoming familiar with.
