What a great reminder from Lily, who, figured out that her frustration was born out of trying to play music that was beyond her skill sets!
Coming to harp as an accomplished pianist, she was anxious to make lots of beautiful music. Being used to sitting down and playing nearly anything she wanted, she approached harp in the same way she'd been treating piano, with frustrating results.
when she slowed down, reviewed early pieces, and focused where her strengths were, the lovely music came back.
And frustration evaporated. And, slowly, one at a time she absorbed new skills.
And her playing improved quickly, without frustration hindering every moment.
Set your sights high, but not too high. Slow steady progress wins the race. If you don't retain your skills and the pieces you learn, you're not doing yourself any favors.
