Now many of the world’s most serious and significant pianists (Schnabel, Serkin, Brendel, Goode, etc.) have devoted a great deal of thoughtful study to the Beethoven sonatas; in general, performance of this music represents a level of erudition and deep contemplation probably unequaled by the works of any other mainstream composer. Serious pianists study every aspect of these works in minute detail; virtually everything is taken into account except those instruments which inspired Beethoven, and which he had in mind when he composed.
The world of music has some resemblance with the natural world. Just as happens in nature with living beings, but at a much quicker pace, musical instruments, genres and styles are created, offered to the public, and then may succeed or not in conquering a place in the musical world. Success and popularity, furthermore, can be fleeting or stable, and their object, in turn, may remain more or less the same for a long time, or evolve. It is not always clear why a particular instrument or genre gains recognition, and another does not; instruments with beautiful timbres fail to survive, and others which are not substantially better become extremely widespread.
