Yeah, I don't mind attending a concert/recital where musicians have scores. In fact I rarely saw concerts without scores on stage.
When it comes to guitar recital, I believe that there is a push for memorization which is good in many ways.
But context is the key:
- When I play at restaurants or weddings, I have my books as I am able to remember 10 repertoire pieces at a time (and sometimes even less)
- if I have to play 2 or 3 solo pieces (when I play with other instruments or lately like I did with a choir), I play from memory
- If I don't have enough time to memorize the piece... I play it with the score (I did that for a party that my aunt organized, she wanted to listen to one piece that I found tricky to memorize... Bach).
When we see a pianist on stage, do we even pay attention if she has a score or not? Darn it, we picked the wrong instrument
