Martha Argerich is unquestionably one of the top pianists in the world. I watched this old video on YouTube when she was rehearsing the Schumann piano concerto and liked what she said about how she approached music. You can watch the video by clicking here. To find out what she said that resonated with me, read below.
"You must try to achieve directness with music. You know, like with a person. If you figure you know how you'll act with someone, it' a fiasco. That's not how it works. You have to be in tune to how that person is at that given moment, not to the idea you have of him."
We should approach God this way too. That is, we go directly to him, remain open and spontaneous (no preconceived ideas), and tune in to him. And great benefits will come through to us.
