Today’s invention is for musicians who are incredibly fussy about how their performance sounds to individual audience members.
The musician would sit on the seat to the left. Each of the audience seats is equipped with a very sensitive microphone, set at head height (red dots).
At rehearsals, a trial audience would be invited in (to ensure that the room acoustics match that of the actual performance).
As the musician turns his head towards each seat, a pair of wireless headphones allows him to hear a faithful reproduction of how his playing sounds at that location (where a small light will turn on).
This enables the player to alter his style of playing, the instrument used or its tuning, so that the performance is optimised. Such an approach could be adopted for every member of an orchestra (perhaps with each player’s instrument emphasised against the background music).
