Back in my student days it was a cumbersome or nearly impossible to listen to different interpretations of a work one right after the other. The school library may have a few duplicate recordings but not many. Today you can hear dozens of different renditions on uTube of just about anything. Try this exercise: Listen to the first minute of a work played by four or five different musicians. Do it again and this time observe the different details of tempo, dynamics, articulation. Observe how the music changes as these details are changed. How does tempo change the character of the melody? How does the articulation change your focus of attention? Is there a counter melody somewhere in the accompaniment? How does this affect the texture? A great piece of music cannot be played fully all at once; it contains more material than can be brought out in a single performance. Learning to listen below the surface can open a whole new horizon of understanding.
