In essence, art lies embedded in the conceptual leap between pieces, not in the pieces themselves. And simply put, there’s a greater conceptual jump from one work of art to the next than from one work of craft to the next. The net result is that art is less polished — but more innovative — than craft. The differences between five Steinway grand pianos — demonstrably works of consummate craftsmanship — are small compared to the differences between the five Beethoven Piano concerti you might perform on those instruments.
