“Let me try to explain it this way. During a performance, it is the conductor who keeps things together, sees that the singers maintain the right tempi, that the orchestra supports them, that the entrances are on time, that neither is allowed to get away from the other. And he must also see that the orchestra’s playing doesn’t get too loud, that the crescendi build and are dramatic but, at the same time, don’t drown out the singers. When a conductor hears this happening, he can quiet them with a flick of his hand or a finger to the mouth.’ To illustrate, the musician demonstrated the gestures that Brunetti had seen performed during many concerts and operas.

‘And he must, at every moment, be in charge of everything: chorus, singers, orchestra, keeping them in balance perfectly. If he doesn’t do this, then the whole thing falls apart, and all anyone hears is the separate parts, not the whole opera as a unit.”
