The link I tried was a string quartet.
I don't play much recorder lately, but they always need something at the Christmas pageant while the little angels are moving back and forth so I had one handy.
I tried reading that string quartet as the score scrolled. I was using the alto in F. (I intended to play the sopranino but the child who's singing had trouble finding the pitch, I changed to the lower instrument.) No problem with violin 1 and 2, but the third stave was in tenor clef. Yes, I read that, a trombone player must, but crashed and burned converting tenor clef to concert pitch to trombone fingering to alto in F fingering. Just couldn't get my brain to work fast enough.
Youtube is an awesome educational resource.
