Agree totally. I have sung onstage many times and have never had more difficulty "hitting the note" as when I had to do a duet. Especially when a passage comes that requires perfect harmony. (i.e. "I've Never Been in Love Before" - Guys and Dolls)
It takes supreme concentration to tune out your partner and perform your part. It takes lots of rehearsing and you have to put yourself inside the music and strive NOT to be a spectator and appreciate your partner's efforts. Often times that is extemely difficult.
Too bad my husband doesn’t sing; he’s mastered the tuning out thing! ;)
I used to sing duets with a tenor who had tremendous power in his voice-I could feel my ears and body vibrating when he would sing his high notes A and up.
I directed the music for Guys and Dolls for a local theatre group-one of my fav shows!!
