I'm learning Muzio Clementi's Sonatina Opus 36, Number 4. In Andante con espressione, there are a number of turns as played in this video (it will take you to the correct time in the video). I had done some studying and learned that a turn is the note above, the note, the note below, and then the note again. However, it doesn't sound like that is what is being played by Cory Hall.
Thank you!
