Theres a lot of discussion here about pitch and AOA which are undoubtedly important. In fact AOA is very important but...
Was the original question not about flying the picture or flying the attitude when he referred to pitch being very important.
If you lost all of the instruments in a light aircraft you could still fly and land it in VMC without difficulty if you had a grasp of attitude rather than flying the numbers.
In any light ac if you covered up all of the insts I bet you could make a decent fist of a landing based on the noise the engine is making and the attitude of the ac outside the window.
Attitude adjustments are far easier to do by looking out the window rather than chasing the ASI. (Ask any IMC student, a peek is worth a thousand scans)
