Answer: The audience want to concentrate on the music, and sometimes on the instruments. But rarely on the musicians themselves.
So why have the orchestra visible at all? Why not have them hidden out of sight behind curtains, in a different room, or even in a different location altogether?
Because watching a group of skilled individuals work in harmony to produce great music is extremely enjoyable.
Some, however, will stand out.
The conductor usually wears different coloured clothes, and is always visible to the audience as well as the orchestra.
Soloists are also often dressed differently, and can usually be identified long before their solo performance by their clothing.
So what do you want to be? Do you want to be the vital but faceless conductor, or the soloist who not only stands out from the crowd, but has their few minutes of glory when they are the sole focus of the entire audience, orchestra and conductor.
The soloist isn’t picked randomly. They have unique skills and individual talents that make them stand out from the crowd, and consequently have more to offer the audience.
Yet having the right skills (features) and talents (benefits) means nothing if no-one knows. Can you see where this is going? Let me know if not!
