Tokyo's symphony orchestras are all engaged in presenting live public performances from the same general body of symphonic repertoire. We expect to enjoy variation in our diet USICthough, not only in meals but also in music. For this reason, orchestras tend to reprogram a work when it can be interpreted under another conductor, for variety.
Musicians all start from the same point, the same black notes on the white page. Differences of temperament, technique and training affect individual interpretations, and distinctions of pacing, nuance and character are easily perceived, just as the same lines sound different when different people read them out loud. Some people make them sound better than others.
